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.

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.

Caption: 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)…

The brilliant cover-art to Switek (2013), by Mark Stutzman. Image: Switek (2013).

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 iconic diplodocid specimen (AMNH 460) on display in the American Museum of Natural History, New York, with its semi-imaginary skull. Long labelled as Brontosaurus excelsus, and then Apatosaurus excelsus, it’s currently of indeterminate status. Image: AMNH, in public domain (original here).

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.

Front cover of Switek (2013). Some apatosaurines truly were gargantuan - the individual shown here might be overly gargantuan, but the image is brilliant anyway. Image: Switek (2013).

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)].

Another fantastic apatosaurine: this is Apatosaurus louisae, photographed at the Carnegie Museum. You might be wondering what the deal is as goes those massive club-like processes on the cervical vertebrae. Yeah, we’re working on that. Really… we are. Image: Tadek Kurpaski CC BY 2.0 (original here).

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.

Another excellent volume on the history of Mesozoic dinosaur palaeontology: Paul Brinkman’s 2010 The Second Jurassic Dinosaur Rush. My review of this book can be found here (at the paywalled and utterly useless no-man’s land that is the SciAm blogs site). Image: Brinkman (2010).

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).

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.

Reminiscing on Tetrapood Zoology: Book One…

Happy birthday, Book One…

There’s a huge quantity of stuff I want to – indeed, need to – blog about. But I can’t. Too much work and not enough time. But something interesting just happened and I feel it’s worthy of mention here. In September 2010, Tetrapod Zoology Book One (Naish 2010) was published (on or around the 27th, to be precise), and thank you facebook for reminding me that eight years have passed since then (yup, the maths checks out). This is painful to hear, because my intention was always to churn out additional volumes in the series every few years: the idea being that I would, by now, be four or five or more books into the series. But no. I despair over how little time I have to do the things I want, and how much there is that I want to do and still haven’t done. It’s on my mind all the time. Why couldn’t I be born rich? Huh.

Caption: if anything might be considered emblematic of Book One it’s giant killer eagles. Golden eagles can and do kill domestic cattle calves. Image: Darren Naish.

Anyway… Tetrapod Zoology Book One was well received at the time of publishing; I know of one published review (Pihlstrom 2011), and the few I’ve seen on blogs and on amazon are fair. The book feels something like a random assortment of essays on diverse tetrapod groups but at least it compiles articles (albeit not all of them) that appeared on Tet Zoo ver 1 back in 2006. Giant killer eagles, British big cats, Indian Ocean giant tortoises, the Ichthyosaur Wars, olms, azhdarchids, eagles owls in Britain, the discovery of the Kipunji, bird-eating bats and more get coverage. Steve Backshall very kindly wrote the foreword.

The book’s existence is owed to Karl Shuker who emphasised to me in a bar one time how getting (quality, ahem) material written for a blog into actual print is worthwhile, possibly a necessity. I’m inclined to agree. Not everyone thinks this way in the age of the internet and digital storage, but I do and I remain attached to books as physical objects. I literally do not remember the ebooks I own but cannot say the same of the dead-tree objects that I associate with the physical spaces where I’ve interacted with them. Wow, that sounded weird. I later discussed the idea with Jon Downes and ended up having the book published through his CFZ Press, though I misunderstood the finances of the deal we made because I’m a freakin’ idiot. Whatever.

Caption: no no NO — you do NOT own too many book already! BUY MORE!!! Digital books don’t work, I tell you. Image: Darren Naish.

A printing error (though you could describe it in another way if you wished) led to the very first batch of this book being called Tetrapood Zoology: Book One on the spine. That initial batch (of around 300 books, I think) sold out and are now much sought after – I’ve retained one copy and I know other people who won’t sell theirs because they like the typo so much. The second printing is technically a second edition (it even says so inside the book); two editions within the space of a year, woo-hoo!

Caption: spot the cryptic typo. Image: Dallas Krentzel.

The excellent cover art was produced by my friend and colleague Memo Kösemen. I don’t think I’ve previously shared the fact that we went through several iterations before deciding on the final version, and here are two of them.

Caption: art by the brilliant C. M. Kösemen. Incidentally - and wholly coincidentally - Kevin Schreck’s movie Tangent Realms: The World of C. M. Kösemen premiered today in New York!

That’ll do. The plan to publish follow-up volumes remains very much alive, but there are several major projects in the way before anything happens there, and there are things in the way stopping those things from happening, and yet other things too that stop those things from happening as well. I’ll get it all done one day. Or maybe I won’t. It sure feels that way at the moment. Gah.

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.

Ben Garrod's new dinosaur books - another three are due to appear very soon. Image: Darren Naish.

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 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: J. W. Kirby.

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.

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. 

Sophie the Stegosaurus - or NHMUK PV R36730, if you prefer - in person at the Natural History Museum, London. I'm sure many of us have an unreasonable number of photos of this amazing specimen. Image: Darren Naish.

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 Naish.

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.

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.
