Up Close and Personal With the Crystal Palace Dinosaurs

Like many of us, I have long enjoyed looking at the Crystal Palace dinosaurs and other prehistoric animal models, created in 1854, still on show more than 160 years later, and providing a remarkable showcase of ancient life as it was imagined at the time. But I’ve only ever seen them from afar. How fantastic would it be to examine them up close? Well…

You’ve seen the Crystal Palace dinosaurs before (or images of them, anyway), but you might not have seen them up-close like this. Neither had I prior to this very special visit. Image: Darren Naish.

Way back in September 2018, I was fortunate enough to attend the Crystal Palace Dinosaur Days event, part of the Heritage Open Days weekend occurring across the UK on the weekend concerned. I gave a talk and also led a tour around the prehistoric animal models (focusing on the reptiles and amphibians alone). Adrian Lister (of mammoth and Megaloceros fame) led a tour too, Mark Witton gave a talk on ‘Palaeoart After Crystal Palace’, and much else happened besides. I also have to mention the 3D-printed models of the dinosaurs made by Perri Wheeler. How I would love for these to be commercially available: I’m sure they’d be a success. So, it was a great event; well done Ellinor Michel and everyone else involved in the Friends of Crystal Palace Dinosaurs group (follow them on Twitter at @cpdinosaurs) for putting it together.

The real thrill, however, was not the talks nor the presence of the amazing and sometimes spectacularly good speakers but the fact that we were awarded special, up-close access to the prehistoric animal models. A dream come true. As you’ll know if you’ve visited Crystal Palace or read about it, the models are located on islands surrounded by a snaking waterway. In other words, they aren’t readily accessible. For the duration of Dinosaurs Days, however, a temporary bridge had been erected and – like Lord Roxton striding across a felled tree to Maple White Land – we made the crossing and stepped into a bygone era.

Why erect a bridge to the islands in the first place? Both so that crucial landscaping and gardening can occur, and so that the models can be examined and evaluated for repair. They’re not in the best of shape, you see, and much work needs doing. Indeed, right now there’s a major push to get funding for a permanent bridge that will allow the continual access that’s required. This project only has a few days of fundraising left and there’s some way to go before the target is reached: go here and chip in if you can. You might have heard that the Mayor of London agreed to partly fund the project… as has legendary musician and song-writer Slash, since it turns out that he’s a big fan! I should add that Slash seems to be quite the fan of science in general, his twitter account revealing a definite tendency to use his powers for good.

The reason I’m writing this article is not just to bring attention to this push for funding, but also to discuss and illustrate various of the remarkable details I got to see thanks to this up-close encounter. Before I start, be sure to read (if you haven’t already) the August 2016 TetZoo ver 3 article on the Crystal Palace models. Thanks to the Dinosaur Days event, I should add that I’ve been able to get hold of the guide that Richard Owen wrote to accompany the exhibition, or the 2013 reprinting (Owen 2013) of this 1864 publication (Owen 1854), anyway. It provides at least some background information on why the animals look the way they do.

I’ll avoid repeating here the same points I made in my 2016 article but I will repeat my primary take-homes. Namely, that it’s disingenuous and naïve to criticise the models as outdated or as inaccurate, laughable follies, as is sometimes done. They have to be seen within the context of what was known at the time, there has to some acknowledgement of the fact that scientific knowledge has improved over time, and there should also be recognition of the fact that the models are more up-to-date than, and superior in technical accuracy and craftmanship to, the vast majority of modern efforts to portray prehistoric life. In the interests of correcting a mistake made in my 2016 article I should also point out that Crystal Palace is not in Sydenham as I stated, but in Penge. With that out of the way…

A lot of detail was added to the megalosaur’s face - some of it is superficially crocodylian-like. Note the ominous cracks at the tip of the nose and along the side of the lower jaw. Image: Darren Naish.

It was a real thrill to see the remarkably detailed appearance of the three Crystal Palace dinosaurs: Iguanodon, Megalosaurus and Hylaeosaurus. Each has a very different skin texture, the Megalosaurus being the most unusual in that it doesn’t have the tile-like scales of the other two. Instead, it’s decorated with a crazy-paving-like covering. It’s not clear what Benjamin Waterhouse Hawkins (the designer and model-maker) was trying to achieve here since this is a rather non-reptilian look. Perhaps the aim was to give the animal a fissured skin texture vaguely like that of elephants.

Holes on the undersides of the Iguanodon and Hylaeosaurus mean that their insides can be inspected. As you can see from my photos, the models look like weird gabled roofs from the inside, numerous metal struts and poles helping to provide support. The hylaeosaur’s original head was removed since its weight was causing the model’s neck to break, and was replaced with a fibreglass copy. So, peer inside the hylaeosaur from beneath and you see the translucent interior of its face.

Cracks, fissures and damaged sections are visible everywhere, moss invades and covers parts of the hylaeosaur’s flanks (not good if you want the models to persist) and sections of the megalosaur’s nose look like they could fall off at any moment. Similar damage is present on some of the other models, their skin and scales flaking or cracking or looking to be in imminent danger of breaking or falling off. Some substantial (expensive) repair work has been done by the Friends of Crystal Palace Dinosaurs, but much more is required.

In my previous Crystal Palace article, I discussed the fact that the models reveal a great many complex anatomical details, some of them involving details only familiar to specialists. When you see the models up close, even more such details become apparent. I’m not sure I knew that the mosasaur is equipped with accurate palatal teeth, for example. Owen specifically referred to this feature in the guidebook (Owen 2013). The temnospondyls (‘labyrinthodonts’) have big palatal teeth as well, as they should.

To Owen and Hawkins, this animal was Labyrinthodon salamandroides, a sort of composite based on temnospondyl bones and teeth, and inferences made from croc-line archosaur footprints, thought by Owen and those who followed his work to be made by Labyrinthodon. Image: Darren Naish.

Like the dinosaurs (except the megalosaur), the surviving pterosaurs are fantastically scaly (today, we think that pterosaurs were covered in a filamentous coat, except on their wings, the distal parts of their hindlimbs and their snouts and faces). Unfortunately, the pterosaur with folded wings has recently been damaged, its smashed snout and lower jaw meaning that you can see right inside its head. This reveals a complex internal ‘anatomy’: another reminder that the models weren’t all built to the same plan or in the same style, but that very different approaches were used for each.

The two large Crystal Palace pterosaurs represent the species known to Owen and Hawkins as Pterodactylus cuvieri (though the possibility that more than one species is represented is raised by Owen’s remarks in the accompanying guide). Unfortunately,…

Unfortunately, one of the models is now badly broken. The two smaller pterosaur models are not currently on display and have had a really unfortunate history: they’ve been vandalised, broken and stolen several times. Image: Darren Naish.

Both big pterosaurs stand atop a small rocky ’cliff’. Like all the geological structures in the park, this is an installation specially created as part of the display. It looks, at first sight, to be made of nondescript grey rock. While looking at it, I began wondering about its specific composition, since we know that the other chunks of rocks in the park aren’t just random lumps of local geology, but transplanted sections of the specific geological unit the respective animal’s fossils come from.

As per usual, the model up-close - this is the Pterodactylus cuvieri posed with open wings - is a remarkable bit of craftmanship. Pterodactylus cuvieri was named for bones that have more recently been included within the genera Ornithocheirus and An…

What, then, are these pterosaurs really standing on? Mark Witton and I examined some freshly broken fragments of the cliff – the rock is chalk! This really shouldn’t have been a surprise given that the fossils these reconstructions are based on come from the English Chalk (Owen 2013), but it was great to see it confirmed. There’s even a line of dark flint nodules, just as there is in real chalk cliffs. These details are surely known to specialist researchers but were news to me.

Broken sections of the ‘pterosaur cliff’ reveal that we’re looking at chalk… which isn’t a surprise, and is exactly what we would expect, but here’s confirmation. You should be able to see a few of the dark, shiny flint nodules too. Image: Darren Na…

Look – below – at the photo of the teleosaurs. Notice how the arrangement of scales and scutes is highly detailed, and how the animals have been given a scute arrangement that very much resembles that of living crocodylians. As it happens, the arrangement they’ve been given is dead wrong for teleosaurs but it is absolutely accurate for living crocodylians (where dorsal scute arrangement is – mostly – diagnostic to species level). What I’m saying is that I think that Hawkins looked at living Saltwater crocodiles Crocodylus porosus when designing these amazing models, since their dorsal scute pattern specifically matches this species (and, surprisingly, not gharials).

As usual, there’s stacks more I want to say, but time is up. I had such a great time seeing the models up close and I can’t wait to do it again. At the risk of sounding like a broken record, the Crystal Palace prehistoric animals are among the most scientifically and historically important renditions of ancient creatures ever created, and they’re amazing pieces of art, construction and craftmanship to boot. A full, thorough discussion of their ‘anatomy’, backstory, construction and history has, even today, never been published – McCarthy & Gilbert (1994) is the closest thing to it – and much remains to be compiled and discovered.

These models must be preserved for the future. On that note, don’t forget to pledge your support for the bridge project. Crystal Palace and its models will be covered here again at some point in the future, and various relevant projects will be discussed here in 2019 – watch this space!

The Second Edition of Naish and Barrett’s Dinosaurs: How They Lived and Evolved

Regular readers of this blog should know that 2016 saw the publication of the Natural History Museum book Dinosaurs: How They Lived and Evolved, co-authored by this blog’s humble overlord… that might be an oxymoron… and the Natural History Museum’s Paul Barrett (Naish & Barrett 2016). Dinosaurs has been well received and pretty successful in terms of sales, and so it came to pass that there was the need for a modified, softback version that included updates and corrections. Officially, the new version is a ‘fully revised and updated’ version, but it’s very literally a second edition, and that’s what I’m calling it.

Naish and Barrett, second edition - with a new cover!

First off, the production of a second edition – we’ll call it Dinosaurs 2nd ed (Naish & Barrett 2018) from hereon – allowed the correction of assorted typos and poor word choices. It never ceases to amaze me how much stuff we miss even when a given piece of text is checked, double-checked and checked again. Big thanks to fan of the book Klinsman Hinjaya for noting a number of required corrections. More importantly, said second edition also allowed us to update or modify various aspects of the science covered in the book. New data and new interpretations mean that our ideas on the biology and evolutionary history of extinct animals are constantly changing, and this was a great opportunity to get some of the relevant changes incorporated.

Some of you – especially those in possession of the first edition – are keen to know what’s different about Dinosaurs 2nd ed, so – without giving too much away – let’s take a look…

A new cover. Personally, I think that Dinosaurs: How They Lived and Evolved is a pretty good book, and I hope you agree. But I never much liked the cover, and I know I’m not alone. Given that it portrays a roaring monster that’s showing us the inside of its mouth and what biiiig teeth it has, it might be construed as being contrary to the message otherwise promoted throughout the book: that non-bird dinosaurs were animals, and not the monsters of Hollywood and popular fiction.

The plan for Dinosaurs 2nd ed was thus to produce a brand-new cover that better represented modern thinking on dinosaurs. Paul and I opted to have either a feathered theropod, or an unusual ornithischian, and we ended up going with the latter for reasons I can’t recall (I think because it might look weirder and less familiar: feathered theropods are so passé, after all). Our chosen artist – Bob Nicholls – came up with a bunch of test sketches, all depicting the Chinese heterodontosaur Tianyulong in various poses and behavioural settings. We chose one, and Bob went to extraordinary trouble to get the contrast, lighting and composition right. There’s much more to it than that but… ladies and gentlemen, I give you… our new cover.

New artwork. Moving now to the insides of the book, we’ve also replaced a few other images that were used in the first edition. Bob has a few more of his excellent images in the book, we swapped out the (now defunct) diagrams on diplodocid jaw movement with a new reconstruction of a ground-feeding diplodocid (though illustrated without the keratinous beak recently proposed for this group), and Matt Martyniuk’s Anchiornis replaces a previous image with a problematic forelimb configuration. I also replaced a bunch of small images used in various of the cladograms.

Necessary coverage of the Ornithoscelida thing. Currently, one of the most talked-about issues within the study of Mesozoic dinosaurs is Matt Baron et al.’s (2017) proposal that the main branches of the dinosaur family tree be rearranged, such that sauropodomorphs are outside a theropod + ornithischian clade termed Ornithoscelida. I wrote about this proposal when it was brand-new, back in March 2017. It has been hotly contested by several teams of authors and there are already a few publications saying how reanalysis does not support Baron et al.’s model, or at least does not support it preferentially above the others that are available.

Obviously, we just had to cover this issue for Dinosaurs 2nd ed – especially so given that Paul is one of the study’s authors – and a few new paragraphs of text and new diagrams summarise the area for our readers. Our coverage of the Ornithoscelida issue resulted in various knock-on changes elsewhere in the book. New phylogenetic positions, for example, have been favoured for herrerasaurids, Eoraptor and so on.

New taxa, new names, new phylogenetic possibilities. The world of Mesozoic dinosaur phylogeny and systematics move fast – remember that an average year right now sees the naming of between 30 and 50 new non-bird dinosaur species. We’re at a stage where phylogenetic models are never really ‘overturned’, but they certainly undergo regular tweaking, modification and augmentation. In view of this, Dinosaurs 2nd ed includes references to Stenonychosaurus, Latenivenatrix (sorry, Troodon) and halszkaraptorines, and I subtly changed the wording on the megaraptorans…

Pisanosaurus is no longer bigged-up as a possible early ornithischian given data indicating that it’s a non-dinosaur.

Revising thoughts on the origins of flight. Those familiar with discussions on both bird and flight origins within dinosaurs will know all about the ‘trees down vs ground up’ argument, and also with the contention that it might be utterly wrong to polarise things in this way. Nevertheless, there remain – for all those attempts to point to shades of grey – extremes in the debate. My take on the earliest phases of maniraptoran flight has mostly involved a weird sort of hybrid whereby the animals concerned are deemed predominantly terrestrial but also capable of climbing, their leaping, fluttering and gliding in arboreal settings being antecedent to flight. Like many people, I was originally enthused enough by WAIR (wing-assisted incline running) to think that it might be a plausible explanation of how maniraptorans first came to exploit arboreal settings and, from there, evolve flight.

Dececchi et al. (2016) showed that at least some non-bird maniraptorans do not have the right combination of anatomical features to benefit from WAIR as originally envisioned. This work affected our thinking on flight origins in Dinosaurs 2nd ed. Cr…

The diversity of non-bird maniraptorans is such that it looks likely that these animals practised all sorts of behaviours during the long time that they were around, and thus that various different acts and adventures could have contributed to their ability to leave the ground. Having said that, recent studies indicate that at least some of the relevant animals could likely leap into flight from a ground-based start (Dececchi et al. 2016), and – at the same time – that arboreal behaviour was unlikely in such species. The possibility that flight could well have evolved without any arboreal component is interesting (and even shocking to some), and sufficiently so that we’ve alluded to it (briefly) in Dinosaurs 2nd ed.

Dinosaurs, the Russian edition. Now I know what my name looks like in Russian. Yes, the title is not the same as the English one.

And that’s it. I should also add that Dinosaurs: How They Lived and Evolved has also recently appeared in Australia (where it’s published by CSIRO), and that a Russian translation is now out as well. My thanks to everyone who’s bought this book, to those who commented on or said nice positive things about the first edition, and to everyone involved in its production and publication.

For those who haven’t purchased a copy, it’s available here from amazon, here from amazon.co.uk, and here from the publishers.

Brian Switek’s My Beloved Brontosaurus: A Belated Review

I’ve posted a few reviews of recently-ish published dinosaur books here lately, aaaand I have a few more to publish yet – the backlog is long. So.. it seemed as good a time as any to recycle this review from five years ago, pertaining to a book published in 2013. The review was written for the website produced to accompany the 2013 Walking With Dinosaurs movie but… for reasons that I’m sure make sense to someone, this review and in fact the entire site was later removed from the internet (yeah yeah yeah... nothing is ever really removed, blah blah blah IT’S GONE FOR NORMAL PEOPLE, OK?). I here republish it in full, unmodified form since those far-off, halcyon days of 2013. Which is kind of ironic, given what’s happened to Brontosaurus since 2013 (see links below for more on that)…

Dinosaurs are popular. We seem, in fact, to be at an all-time high in terms of our hunger for new dinosaur news, the frequency with which new discoveries are announced, and in the sheer volume of dinosaur-themed books, TV shows and movies.

Brian Switek’s My Beloved Brontosaurus describes the author’s personal journey as he visits various dinosaur-bearing fossil sites and dinosaur-themed museums and other institutions across the United States, all the while discussing the fast-changing pace of our knowledge, the new insights we have into dinosaurs and their biology, and the fondness we retain for the big, fat, swamp-dwelling, pea-brained version of the dinosaur that almost refuses to die. Herein lies the explanation for the book’s title: the concept of ‘Brontosaurus’ embodies a defunct stereotype, a name that ‘shouldn’t’ be in current use [UPDATE: OH THE IRONY] and which remains associated with a version of the dinosaur that pre-dates the Dinosaur Renaissance.

The book reads like something of a road trip, arranged such that Switek tells the story of the dinosaurs’ Triassic origins and gradual rise to dominance, explores ideas about their sex lives and reproductive and growth strategies, looks at their evolution of giant size, at dinosaur social lives, at feathers and featheryness, at pathologies and illnesses, and, eventually, at the end-Cretaceous extinction event. It’s a well-written, flowing narrative; the chapters are connected, both to one another and to Switek’s journey across the country, though the connections do sometimes seem a bit contrived. Notes at the back point the reader to technical sources for the information included, illustrations appear throughout, and the book is fully indexed.

I really like Mark Stutzman’s cover art so was especially thrilled to see that the dust jacket folds out into a double-sided poster. Extra dino-geek points if you know the inspirations behind either of Stutzman’s illustrations.

By and large the volume is up-to-date and factually accurate, but there are a few things I take issue with. The name Brontosaurus is of course a major fixture throughout the book, the obvious reason for this being that the name loomed large in virtually every single popular dinosaur book prior to... well, prior to some surprisingly recent date. As Switek explains, it’s not true to say – as people sometimes do – that “Brontosaurus never existed”; rather, the species that the name Brontosaurus is tied to was shown in 1903 to be so similar to species included in another genus (Apatosaurus) that separate status for Brontosaurus was no longer defensible. If Brontosaurus ‘died’ in 1903, why has it persisted until so recently? [UPDATE: AGAIN… OH THE IRONY. For the one or two of you that don’t know, the name Brontosaurus was resurrected from synonymy in a comprehensive analysis published in 2015 (Tschopp et al. 2015)].

Switek’s answer is that this choice was essentially arbitrary: he suggests that New York’s American Museum of Natural History stuck with the name in their massively popular museum display because they maybe “thought the old name sounded better, or were unsure about rebranding one of the most famous dinosaurs in their halls”.

However, as explained in Paul Brinkman’s 2010 book The Second Jurassic Dinosaur Rush, there’s a good reason why Brontosaurus persisted for so long. That reason: Henry Fairfield Osborn, president of the AMNH between 1908 and 1933. Osborn was hugely influential and highly opinionated, and his insistence on sticking with the name Brontosaurus ensured the use of the name well beyond its time as a popular (rather than technical) moniker. The 1903 sinking of Brontosaurus was suggested by Elmer Riggs. Riggs did good work, but he simply lacked the academic clout to make Osborn change his mind.

Something I think we need to do more when writing about scientific discoveries and hypotheses is discuss the social dimension to science: that is, the reception said discoveries and hypotheses received within the academic community. New and radical notions and proposals are – despite the impression you might get from TV shows and magazine articles – typically not embraced with open arms. Instead, they initially receive cold and even harsh treatment. Since scientists are human, the way they react to such ideas may be influenced by their personal feelings, the research environment they were trained in, who their friends and enemies are, and so on. In the world of palaeontology, it seems that we’re entering a phase where we’re increasingly analysing the work and ideas of the last few decades: in other words, charting the socio-political background to the science.

It is important, I feel, that we document the history of our changing ideas, something I tried to do in The Great Dinosaur Discoveries (Naish 2009). Image: Naish (2009).

It is important, I feel, that we document the history of our changing ideas, something I tried to do in The Great Dinosaur Discoveries (Naish 2009). Image: Naish (2009).

I tried to do this myself in my 2009 book The Great Dinosaur Discoveries (Naish 2009), and Switek often does it in My Beloved Brontosaurus since he quotes experts and reports the conversations he has with them. People interested in the history of palaeontology, and in the history of science in general, should read the book for this reason. It helps make the book a snap-shot of where we are now in the world of dinosaur science – it covers the issues we’re currently interested in; the questions and discoveries that we’re talking about.

All in all, My Beloved Brontosaurus is both a fun and absorbing read as well a good, popular guide to our current understanding of dinosaurs and their evolution.

The Last Day of Dinosaurs in the Wild

On Sunday 2nd September 2018, the immersive, interactive time-travelling visitor attraction known as Dinosaurs in the Wild closed its doors for the last time… Yes, Dinosaurs in the Wild is now officially off-show,

and if you didn’t get to see it before that fateful Sunday… where were you? I was determined to embark on one final tour, and of course I also needed to go to the grand send-off party and say those sad final goodbyes…

As discussed at Tet Zoo several times already (all at ver 3, I hasten to add), I was scientific advisor for this grand project and thus very much feel that the look, behaviour and biology of the Late Cretaceous animals brought to life for the experience was and is ‘mine’, the MAJOR disclaimers being (1) that a whole team of people actually did the work that resulted in the vision coming to fruition, and (2) any ideas that I have about extinct animal biology or appearance or whatever involve the proverbial standing on the shoulders of giants, and the work and discoveries of a great many other people.

As with any project of this size and scale, there's the long process whereby models and other props come together over time, and then there's the concept art, the explanatory diagrams, and so on. I've kept a record of as much of this stuff as I coul…

With its fully – indeed, extensively – feathered dromaeosaurs, fuzzy-coated, muscular tyrannosaurs, terrestrial stalking azhdarchid pterosaurs (cough cough Witton & Naish 2008 cough cough), sleek, chunky mosasaurs, balloon-faced ankylosaurs and more (Conway et al. 2012), Dinosaurs in the Wild has – I really hope and feel – introduced a substantial chunk of the human public to a very up-to-date view of the Mesozoic world, and has thus gone some way towards undoing the damage of Jurassic World. No to the scaly, shit-brown, roaring monsters of the past, and yes to a more interesting, biologically plausible and often more surprising view of what these animals were like. Incidentally, Colin Trevorrow visited Dinosaurs in the Wild within the last few weeks, spoke to our associate live action director Cameron Wenn, and said really positive things (Colin and I spoke briefly over twitter).

Here are two of the (normally nocturnal) Dinosaurs in the Wild animals seen in full illumination. At left, the metatherian mammal Didelphodon; at right, the small dromaeosaur Acheroraptor (it never stays still for long, hence the motion blur). Image…

And did Dinosaurs in the Wild have an impact on the public? I don’t know if I’m allowed to release all the figures, but I will say that many thousands of people attended the experience during its 13 or so months of operation at Birmingham, Manchester and London. Our amazing actors and other staff all became worthy ambassadors of ‘new look’ Mesozoic animals and their biology, and the substantial amount of scientific content included in the show surely introduced the public to a great deal of information they haven’t seen or heard before. All results indicate that we certainly received the sort of feedback and accolade we hoped for: we scored really well as goes visitor feedback, indeed sufficiently well that Dinosaurs in the Wild can be regarded as a world class attraction. The palaeontologists and other scientists and experts who visited were all extraordinarily positive, and thanks indeed to those colleagues of mine who voiced their thoughts in public (Dean Lomax, Mark Witton, Albert Chen, Dave Hone, among others).

Our venues were all great – Manchester’s Event City was certainly quite the sight to behold – but were perhaps not as centrally placed as might be ideal, though there are all kinds of factors controlling where and how a given exhibit can be located.

Even now, and even after me writing that fairly substantial ‘behind the scenes’ article I published at Tet Zoo ver 3 in July 2018 (and here’s assuming that SciAm haven’t removed it due to an issue with image rights, ha ha ha), there’s a huge amount that could be said about the ‘making of’ this project. As some of you already know, the backstory to the world of Dinosaurs in the Wild is already written-up in an extensive document that we took to referring to as The Bible, but despite efforts I’ve had to give up on plans to get it published. I will be talking about much of the ‘behind the scenes’ stuff at TetZooCon this year (BUY TICKETS HERE), however, and will be bringing The Bible along for those interested in seeing it.

Huge thanks to everyone at the event last night, and to everyone who made Dinosaurs in the Wild the success it was. Special thanks to producers Jill Bryant and Bob Deere, creative director Tim Haines, the team at Freeman Ryan, to live action directors Scott Faris and Cameron Wenn, to all the amazing people at Impossible, Milk VFX and Crawley Creatures, to every single one of our amazing actors, to our support staff, our sponsors and everyone else. And thanks also to Sam, Simon, Heather and the others who accompanied me on the same, final tour I took just yesterday.

A 1996 Letter from Dr Phil Currie

I think I might get into the habit of posting short articles here: putting longer pieces together takes a while and is often difficult to do in view of other work (hint goddam hint). Let me know what you think about this. Anyway...

The book includes pterosaurs... which is weird but in keeping with the 'evolution of flight' subtitle. Image: Darren Naish

I used to write a lot of letters. I mean: physical, printed letters, on paper. Some of them resulted in interesting things, and others didn't. During the mid-1990s, I obtained and read Philip Currie's 1991 book The Flying Dinosaurs, richly illustrated by Jan Sovak and showing many animals brand-new at the time. And it has some weird stuff in it that had me curious (I won't start discussing that "weird stuff", as it will take me a while to find it in the book, explain it, and put it into context). I managed to obtain Dr Currie's postal address, and wrote to him. And I was thrilled to get a response! Here it is...

Philip-Currie-letter-1996-Aug-2018-Darren-Naish-Tetrapod-Zoology.jpg

Please understand that I am not, in any way, sharing this to shame Dr Currie - heavens, no. I merely opted to share it because it's (for me) an interesting piece of personal history. And it also shows what the situation was - and/or is - like for many busy academics. Today, I know this pain all too well. Modern correspondence, of course, has mostly changed from paper letters to emails. I'm not as famous as Dr Currie, but even I get so much correspondence that I either have to deliberately ignore some of it, or put it to one side such that I can 'deal with it later', only for 'later' to become 'never' as other things destroy those various other plans. I would like to remind others of this when they start sending reminder messages about the responses they'd like. Sorry: there comes a point in life when it is IMPOSSIBLE to keep up with correspondence.

Anyway, I was later to meet Phil Currie on one or two occasions and talk with him about a whole bunch of stuff. Here he is (standing) at a London-based conference that happened in May 2008...

New Dinosaur Books, Part 2: Ben Garrod’s ‘So You Think You Know About… Dinosaurs’ Series

Today we press on with my brief(ish) reviews of recently(ish) published books on Mesozoic dinosaurs – I have quite a backlog – and this time it’s…. the So You Think You Know About… Dinosaurs books, by Ben Garrod. Ben is a qualified zoologist and TV presenter, perhaps best known for the BBC 2014 series Secrets of Bones. I should also add that Ben spoke at the 2017 TetZooCon, so now you know he’s awesome.

Anyway, Dr Garrod has now made a foray into the World of Mesozoic Dinosaurs, and a pretty respectable foray it is. These small, compact books – they remind me of the Horrible Histories volumes a little – provide a huge quantity of information on the dinosaurs they cover, do so in a fun, attractive way, and are very much on-the-ball as goes the current state of our knowledge. They are very much science advocacy tools that don’t shy away from presenting and discussing such topics as complex as sexual selection and evolutionary arms races. The dinosaurian nature of birds is emphasised – dinosaurs can’t be extinct so long as around 10,000 of them are currently alive – and the books are good at conveying the phylogenetic position of the relevant dinosaurs and where they fit within geological time.

Black and white cartoons, diagrams and other images are on virtually every page. If you move in the same social media spheres that I do (I’m @TetZoo on Twitter and Instagram) – surprise! – the cartoons are by Ethan Kocak, and illustrations and diagrams by Gabriel Ugueto and Scott Hartman also appear within.

Excellent illustrations by Gabriel Ugueto appear in each of the books. Hey, Gabriel and I actually worked together on a large poster about tyrannosaurs included in a magazine -- it was published early in 2018 but I still haven't seen it because the …

Excellent illustrations by Gabriel Ugueto appear in each of the books. Hey, Gabriel and I actually worked together on a large poster about tyrannosaurs included in a magazine -- it was published early in 2018 but I still haven't seen it because the publishers never sent me a copy and no longer have any to provide. Huh. Image: Gabriel Ugueto/Ben Garrod/Zephyr.

Regarding what I said a moment ago about these books reflecting ‘the current state of our knowledge’, I’m especially pleased to see inflatable nose balloons featured in the Triceratops volume (for more on this issue see this Tet Zoo ver 3 article from 2016). The Diplodocus volume has a brief discussion of the whole trunks issue (covered here at Tet Zoo ver 3).

Ceratopsian nose balloons go mainstream (images by Ethan Kocak). I can't take credit for this. Or can I. Images: Ethan Kocak/Ben Garrod/Zephyr.

Quibbles: two or three maniraptoran silhouettes are shown as un-feathered, and I will forgive the Tyrannosaurus book for using the full binomial throughout even though the dinosaurs of the other books are only ever mentioned by their generic names. T. rex exceptionalism, we call it.

It's nothing to with Ben Garrod's books, but I thought I'd include another image of ceratopsian nose balloons for good measure. This brilliant piece is by J. W. Kirby and the original can be seen here at KirbyniferousRegret's deviantart page. Image:…

I really like these books and strongly recommend them for young readers (I suppose the target audience is kids between 6 and 16, or so). Ben is big on ‘embracing your inner geek’, and on encouraging young people to be proud of their curiosity and interest in science and nature, and I’m sure this is something that everyone reading this wants to see promoted and celebrated too. Three additional volumes – on Spinosaurus, Velociraptor and Stegosaurus – are finished and due to appear in print very soon (so I understand).

New Dinosaur Books, Part 1: Barrett on Stegosaurs

I’ve always reviewed books here at Tet Zoo, and here at ver 4 I fully intend to condition this fine tradition. Over the next few articles I’ll be discussing new (or newish) books on Mesozoic dinosaurs. And we start with something very special – a whole book devoted to stegosaurs. This might be a first (UPDATE: I just remembered that the late Beverly Halstead wrote a semi-fictional book on the life history of Stegosaurus).

Cover of Barrett (2017)... perhaps the only published volume fully devoted to stegosaurs and stegosaurs alone.

Cover of Barrett (2017)... perhaps the only published volume fully devoted to stegosaurs and stegosaurs alone.

Stegosaurus: An Extraordinary Specimen and the Secrets it Reveals by Paul M. Barrett tells the story of ‘Sophie’ (initially ‘Sarah’, and technically NHMUK PV R36730), the excellent, complete Stegosaurus specimen discovered and excavated at Shell, Wyoming in 2003/4. You’ll have seen this outstanding specimen mounted on display if you’ve visited London’s Natural History Museum. Already Sophie has been the focus of a whole bunch of quality technical publications by the author and his colleagues (Brassey et al. 2015, Maidment et al. 2015, Lautenschlager et al. 2016).

A look inside. This is an info-packed book with great graphics and loads of photos and diagrams.

The book does so much more than tell the story of Sophie: it’s also a very good review of what we know (or think we know) about stegosaur biology. The text is dense, packed with scientific content, and highly readable. Excellent images appear throughout, ranging from photos of the specimen and CT renders generated during research to life reconstructions and maps. I initially assumed – no offence intended to the author – that this would be a text-light book written for kids, with more space than text on its pages. That’s not the case at all: there’s a ton of information here and anyone interested in dinosaurs should get this book. Older kids with an interest in science or dinosaurs will enjoy it, and adults will too. Some of the taxonomic conclusions discussed in the review of stegosaur diversity – that Hesperosaurus is synonymous with Stegosaurus and Miragaia is synonymous with Dacentrurus – have been overturned in work published since the book saw print (Raven & Maidment 2017).

A reminder that the stegosaurs of your parents or grandparents - or those of a recent terrible movie franchise - are not in keeping with the way these animals more likely looked. These drawings are old, excuse the GSP tail muscles. Image: Darren Nai…

In short: highly recommended for everyone, and dead cheap as well.

Disclaimer: the author and I previously worked together on another dinosaur book published by The Natural History Museum, namely Dinosaurs: How They Lived and Evolved (Naish & Barrett 2016). As some of you know, a second edition of that book – including numerous tweaks and updates – appears in print very soon, so I’ll be talking about it then.

Stegosaurs have been covered quite a few times at Tet Zoo previously. See…

Things are going very well here at ver 4: I’m keeping an eye on the hits counter and the comments, and things are good. Many thanks to everyone who’s helping to make it work. Here’s your reminder that the more support I receive at patreon, the more time I can spend writing and publish the stuff you like to read. Thanks to those who support this endeavour already. As a Tet Zoo patron you get to see stuff coming together behind-the-scenes: there are already over 550 in-prep illustrations and pieces of text there.
