Book Review: Tales of Prehistoric Life by Daniel Loxton

This spring, Daniel Loxton published his third and final children's book in the Tales of Prehistoric Life series: Plesiosaur Peril, the story of the dangerous life of a young Cryptoclidus in the Jurassic. It was proceeded by Ankylosaur Attack (2011) and Pterosaur Trouble (2013). Today I'll cover all three. The TL;DR version: they're great.

Daniel Loxton's name is probably recognizable to the portion of our readers who also follow skeptical media. He cowrote Abominable Science with Donald Prothero as well as writing and illustrating the children's book Evolution: How We And All Living Things Came to Be. Loxton is also well-known for his work editing the Junior Skeptic section of Skeptic Magazine. Illustrator Jim WW Smith, who has also worked for Junior Skeptic, provides work on the models for the Tales of Prehistoric Life series. Loxton provides the finishing textures and colors, as well as photographing environments.

I especially appreciate Loxton's series for taking up the mantle of the Rourke titles we've covered so many times during the Vintage Dinosaur Art series. Like the Rourke collection, each Tales of Prehistoric Life book is a narrative story, detailing interactions between temporally and geographically appropriate animals. I love this approach. When grounded in modern paleontological understanding of the life and times of the animals involved, it's both engaging and educational. Like the Rourke titles of yesteryear, each book in this series also wraps up with a brief explanation of the scientific grounding of the story.

The animal interactions are firmly in the realm of plausibility. There are moments that seem a bit of a stretch, such as a veritable army of Saurornitholestes laying seige to the Quetzalcoatlus hero of Pterosaur Trouble. However, there's nothing more outlandish than Dinosaur Revolution's more slapstick moments. Since I'm on the record of admiring much of what that series did, you can predict my reaction here. When the Quetzalcoatus quad-launches to escape his attackers, one of them inadvertently hitches a ride before being flung onto the head shield of a Triceratops, and I couldn't help but crack a smile.

3D dinosaur art is too often only mentioned when picking out the worst offenders, so it's easy to forget that it is often done very well, and Loxton's work here is a prime example. For the most part, the animals are integrated into their photographic environments very smoothly, and interact with them believably - there is a sense of weight and heft to the animals as they walk on sand, browse vegetation, or fall into water. The experience is an immersive one, with illustrations filling entire spreads. The point of view is often right in the middle of the action. Loxton's attention to detail rewards free exploration of the environments and their inhabitants. Feathers float on the air in the midst of combat. Age and experience are obvious, as in an old ankylosaur with battle-damaged armor or a pycnofibre-covered pterosaur.

Coloration is handled conservatively. There are no Rey-style color schemes. Proto-birds and dromaeosaurs are given the most colorful integument. I particularly liked the ruddy tones of Saurornitholestes, reminiscent of the Brown Thrashers who inhabit a similar woodland habitat in my neck of the... er, woods. I also enjoyed touches like subtle sexually dimorphic coloring on the Triceratops, and a seaweedy-green on the Cryptoclidus family at the heart of the most recent book. The tyrannosaurs who appear in Ankylosaur Attack and Pterosaur Trouble could do with some plumage and a splash of color (as well as some more neck musculature, which to my eye looked a little skinny). On the other hand, it's refreshing for the tyrant king to step out of the spotlight.

Loxton's choices in depicting behavior are the strongest aspect of the stories, as pains are taken to focus on details of Mesozoic life lent us by recent paleontological research. Quetzalcoatlus falls prey to small dromaeosaurs because of tooth marks found on actual fossils of the great azhdarchid. It bears repeating that the pterosaur is depicted performing a quad-launch, too (a touch which pleased Mark Witton greatly). The family unit in Plesiosaur Peril is based on evidence that these marine reptiles were viviparous. It's a stretch to lump Loxton's book series in with the All Yesterdays Movement. But it is certainly complimentary in its dedication to anatomical fidelity and reasonable inference, while offering views of prehistoric life which reflects the way extant animals act rather than what Hollywood dinosaurs are asked to perform for the masses. There's no need to layer on excessive personification or spectacle after spectacle. Loxton's adherence to this is the main reason the books succeed.

My only major critique is that a more readable typeface for the body copy of the books could have been chosen, but that's a small quibble in the big scheme of things. This is as good as prehistoric fiction gets. The life restorations are exactly the kind that the new generation of paleontology fans should have access to: contemporary, not stuck in decades-old knowledge. All books in the series are available at major booksellers or via Skeptic.

Around the web: Check out Loxton's post about Plesiosaur Peril at SkepticBlog. Darren Naish wrote a detailed post about the book at TetZoo - fitting since he served as technical consultant for the whole series. Adam Stuart Smith reviewed Plesiosaur Peril at Plesiosauria.com. Dispersal of Darwin's Michael Barton reviewed Plesiosaur Peril in March (and reviewed the other titles in the series previously). Ankylosaur Attack recieved positive reviews from Quill and Quire, Kirkus, and SkepticDad.

Archosaurs of Alabama

Welcome back, everybody! Where last we left off, I'd done a brief, illustrated survey of some notable Alabama Cretaceous marine fauna. Here, we turn out attention to some of the archosaurs that would have lived in the parts of the state not covered in seawater. 

I speak, of course, of dinosaurs. Mostly. 


Image
Nodosaurid  © Asher Elbein
Alabama has quite decent nodosaur remains, most of them the product of carcasses washed out to sea by floods and river currents. There, the bodies bloated and were extensively scavenged before they sank to the bottom. This is my first ever attempt at an armored dinosaur (or at least, the first I'm willing to show in public) and I initially thought of restoring it with bright warning coloration, similar to that of a hornet or a yellow jacket. Suffice to say, it didn't really work, so I defaulted to a more hippo-like pattern instead.

 I'm somewhat taken with the idea of nodosaurs dozing in mudpits, small feathered dinosaurs perching on their spikes. It might be worth illustrating at some point.

Image
Lophorhothon © Asher Elbein
Lophorhothon is Alabama's main hadrosaurid, and like the nodosaur remains it occurs primarily in marine deposits. It has the twin dignities of being both Alabama's first recorded dinosaur genus and being one of its most taxonomically uncertain; there's some debate as to where, precisely, it fits with regards to other hadrosaurs (or if it's even a hadrosaur at all.) Following the prevailing opinion, I went ahead and restored it as something similar to Prosaurolophus. I wanted something restrained and somewhat dignified, so I turned to a color scheme reminiscent of African grazing mammals.

Image
Dromaeosaurid  © Asher Elbein
The most speculative reconstruction of the bunch. Dromaeosaur fossils in Alabama are extremely rare, centering around a few scattered bits and a preserved feather or two. It's not that surprising; small size and light bones make dromaeosaurs fairly chancy when it comes to preservation, and in marine deposits the likelihood of a carcass lasting is virtually nil. Given that, this is best understood as guess at what an Alabama dromaeosaur might look like.

 I took this illustration as a chance to play around with some different ways to render feathers (I'm particularly proud of the neck region.) The patterns are based--extremely loosely--on the Caracara, a modern raptor that spends a fair amount of time on the ground.

Image
Appalachiosaurus © Asher Elbein
No Cretaceous dinosaur assemblage is complete without a big theropod, so here we have Appalachiosaurus, the 30 foot tyrannosaurid. Appalachiosaurus also has the distinction of being the most completely known theropod from the eastern coast of North America, a part of the country that lacks the excellent fossil fields out west. The mounted specimen at the McWayne Science Center shows large, three clawed arms. I'm unsure of the accuracy--nothing has apparently been published yet--so I chose to restore Appalachiosaurus as a fairly typical albertosaurid. I gave it a sparse covering of protofeathers on the head and neck, and based the coloration on that of the Emerald Swift, an extremely pretty little lizard common in Central America. There was no particular scientific reason for doing so; I just liked the challenge of adapting the color scheme to an animal of radically different size and shape.

Of all of the reconstructions, this is the one I suspect is going to be rendered invalid by later publications, but one of the nice things about paleontological art is that it affords you the opportunity to make guesses that may or may not be correct.

Image
Pteranodon © Asher Elbein
Finally, Pteranodon. Probably the most famous animal in this post, and naturally so. Everybody loves Pteranodon. I chose to reconstruct this particular beast with the wing arrangement favored by John Conway, as I've always found it very aesthetically pleasing. I also gave the animal a small mane under the crest, which would fluff up for display purposes. I decided to avoid the typical sea bird coloration for this illustration. While there a good reasons to believe that Pteranodon might have been so adorned, I wanted to try something different; to wit, a giant fruit bat. I also chose to make the crest less brightly colored, again for the sake of being contrary.

And that's it, folks! This artistic summary of Alabama's Cretaceous life now draws to a close. If you liked the art, feel free to head over to ashere.deviantart.com, for all your folkloric and dinosaurian needs.

Tune in next time for more comic book dinosaurs and a dissection of why, exactly, The Valley of Gwangi is so great.

Vintage Dinosaur Art: The Quarry Shuttle at Dinosaur National Monument

I have a John Sibbick book of my own to share, but I've decided to hold back and give the kind readers of LITC a little break. Instead, today I'm sharing a collection of dinosaur illustrations that decorate the shuttle which operates within Dinosaur National Monument, taking visitors to the visitor center protecting its most famous landmark. In keeping with the monument's focus on the history of paleontology, they are throwbacks to the saurians of mid-century dinosaur books, possibly one we might have featured in this ongoing series.

UPDATE: Indeed they are - readers have pointed out that these are derivative of the Giant Golden Book of Dinosaurs, featuring Rudolf Zallinger's work. That's one I've wanted to find for a while but never have.

The paintings, which encircle the shuttle's two trailers, covering just about every panel large enough to accommodate artwork, are the work of Kay Thunehorst, an obscure artist with zero presence on the toobs. I've put out feelers to find when these paintings were made, and will update with what I find out.

The Quarry Shuttle

Continuing the tradition of presenting iconic non-dinosaurian creatures alongside the bona fide members of the tribe, the shuttle includes Dimetrodon and a Pteranodon gracing the front of the shuttle.

The hadrosaurs are represented by Lambeosaurus and the taxonomic mess of Trachodon.

The shuttle wouldn't feel right without sauropods, of course, and Thunehorst has painted Diplodocus and a traditional, swamp-bound Brachiosaurus.

The third sauropod is a return to one of my favorite tropes: Gory theropod attacks on the docile giants. Here it's the vicious Allosaurus grimly dispatching poor ol' Brontosaurus UPDATE: It's also a copy of Zallinger's take on this battle, as you can see here.
The Quarry Shuttle

Yes, there be theropods on the shuttle, as further attested by this generic member of the clan, as well as the mandatory Tyrannosaurus and our little buddy Compsognathus.

These illustrations are not technically proficient, but they bear a primitive charm, and their weathered look adds a certain poignance to them. It was a pleasant surprise to see Thunehorst's cross-section of the dinosauria (pluss a couple oddballs) on the shuttle. Outdated illustrations like live on as reminders of how far we've come in the last few decades. Long may they decorate the shuttle to the Quarry Visitor Center. Speaking of which, my next post will bring us face to face with its famous wall of fossils. Special thanks to David Prus and Christina Wilsdon for pointing out the heritage of these pieces from the Zallinger illustrations.

Roadside Saurians

A month or so ago, Jennie and I departed the great American Midwest for the much greater American West, in an exploration of a landscape that has been etched on my memory ever since I first glimpsed it as a kid. I've only passed through or flown over since then, so this two-week ramble around the Great Basin was long overdue. In planning the trip, we were a bit overambitious, and though we had trimmed it back once already, by the time we hit the road and got a feel for how long things actually take, we rearranged things again to lessen the amount of time driving. Hint: arriving at the gates of a national park usually entails another couple hours of driving.

Along the way, I took gigabyte upon gigabyte of photographs, which I'm only about a third of the way through sorting and processing to share at Flickr. These photos naturally included the dinosaurs we saw along the road. I'll start my short series of posts inspired by the trip with some of these charismatic creatures of the Mesozoic.

My favorite was a Spinosaurus perched outside a rock and fossil shop in Orderville, UT, a small town sitting between Bryce Canyon and Zion National Parks. As we rounded the bend in Rt. 89 into town, this guy came into view, and it was impossible not to stop.

Roadside Spinosaurus

Not the most accurate by-the-book spinosaurid you'll ever see, but refreshingly depicted in a posture that's kind of right.

Roadside Spinosaurus

For sheer volume of roadside dinosaurs, it's hard to beat Vernal, UT, a short drive from Dinosaur National Monument. Some have seen better days, such as this dopey pink sauropodosomething.

Roadside Dinosaur

Outside of a hotel, there's a green, spiky-backed sauropodosomething with a rather uncomfortable electronic sign on its neck.

Roadside Dinosaur

There's also a T. rex, naturally depicted in classic man-in-suit posture, as any red-blooded American tyrant dinosaur should be. He's also a bit of an angler, it would seem.

Roadside Dinosaur

The best Vernal has to offer is a Morrison tableau featuring Ceratosaurus, Stegosaurus, and Camarasaurus.

In what must be a show of Jurassic herbivore solidarity, the young Camarasaurus has found a savior in Stegosaurus, which ably deploys its thagomizer in its defense...

... by bashing him in the tender underparts.

You want a close-up of that, don't you?

As you approach the Utah entrance of Dinosaur National Monument, a gift shop boasts a big green sauropod of its own. Like most sauropods you see on the side of the road, the sculptor likely had no specific taxon in mind. Just a long neck, long tail, and some pillar legs, and you've got what springs to 90% of folks' minds when they hear the word "dinosaur."

Now that we've come to the gate of DNM, we'll be entering the park to check out the new quarry visitor center. Before that, I'll share some vintage dinosaur art photographed in a surprising place. Stay tuned!
