Nightmare Mouths of The Permian

Did you know that some prehistoric amphibians have terrifying teeth covering the entire roofs of their mouths?? Prehistoric monster teeth experts from the University of Toronto Bryan Gee, Yara Haridy and Dr. Robert Reisz have determined how the bizarre teeth covering the roof of the mouth of some prehistoric amphibians such as the chihuahua sized Cacops pictured above developed. It turns out, all of the thousands of tiny teeth these bizarre creatures used to capture and perforate their prey were made of the same ingredients as the teeth around the rim of their mouths, but bizarrely these teeth are not on the jaws, but rather on tiny plates of bone embedded in a flexible layer of tissue on the roof of the mouth. To make things extra nightmarish these tooth-carpets covered empty spaces in the roof of the mouth that their eyeballs would push down into when they swallowed, just like a modern frog. Except unlike a modern frog their eyeballs pushing into their skull would press the teeth down into the prey like a godawful amphibious iron maiden that can swallow you (if you’re a small animal).

And you can check out the University’s official press release with a video of David Attenborough feeding a bug to a giant monkey frog (with psychadellic skin secretions btw).

One of the things that really hooked me (puns intended) into doing this quick reconstruction of this wondrous little horror from deep time was the environment. Mark MacDougall et al 2017 describe the strange depositional environment that the skeletons of the creatures pictured in my reconstruction were found in. Turns out these fossils were deposited in an ancient limestone cave system, and some of the skeletons were found with calcite cave formations grown into and around them!

It’s unclear at this point whether the animals were actually living in the upper parts of the cave and got trapped deeper down, as well as washed in by seasonal storms from some outside environment, but the area around these caves in the Permian would have been semiarid, so we thought it was reasonable to speculate that these armored amphibians would’ve been hiding amongst the limestone boulders and crevices that were likely found around the entrances to these caves.
A few months back I just so happened to be exploring a similar modern environment in Nevada, where upthrust limestone has been eroded by water to form numerous caves of various sizes.
One of the things that struck me was how much cooler and more moist the caves were than the surrounding desert – even just a few feet within the entrance. I also found evidence of animals using the caves, from birds and small invertebrates to mountain goats and puma, who had littered the floor of one of the larger cave entrances I explored with a thick mat of goat poop and goat skeletons, one of which had been recently fed on by a puma.
Thus I thought it would make sense to show a similar dynamic happening at the entrance to a small cave in the permian, with both predator and prey utilizing this uniquely productive micro ecological space to survive in a harsh desert environment…

Just a reminder that if you are time traveling and exploring small limestone caves in Oklahoma about 289 million years ago, be careful when putting your hand into small crevices. A Cacops biting you would feel like the world’s slimiest/toothiest bear trap clamping down on your hand and mashing it’s toothy mouth-roof into your flesh by pulling in its damn eyeballs.

Aquilops Revisited

Ever since reconstructing Aquilops in 2014 I’ve been wanting to revisit it to explore another idea for it’s life mode and role in the ecology. Spurred by the request of Dr. Andrew Farke and Gabriel Santos to do a talk about making monsters and reconstructing prehistoric animals, I finally got around to illustrating this new interpretation.

2015 in Review

2015 was a busy year. Here’s some of the stuff I finished during our last rotation around the sun…

Sort of as an experiment in minimalism, I made this music video for a track in collaboration with beatmaker BLAQ MASQ

I also recorded several other verses for musical collaborations, such as this one (the others have yet to be released):

I also designed and animated several minutes of animation for a TV documentary about viking mythology. Here’s a short clip of some of my animation. I plan on assembling all of it as a standalone short as soon as I can find the time:

On the front lines of paleoart, I launched the #buildabetterfaketheropod hashtag along with a pile of art poking fun at the dinosaurs/science of some dinosaur movie that came out this year and was sorta big.

Somewhere around that same time I went out to Moab Utah to photograph and explore the Mill Canyon Dinosaur Trackway, which I then created an illustration of for an interpretive sign commissioned by Utah BLM Paleontologist Rebecca Hunt-Foster.


Later that summer I traveled out to Utah again to participate in my first paleontological field expedition, again with ReBecca Hunt-Foster, her husband John Foster, Sharon McMullen, Mikey Schiltz and Matt Wedel to survey a newly discovered secret site, cluttered with mid mesozoic dinosaur fossils and giant petrified trees! That was awesome. But I can’t say more because it’s all still super secret and I’d be beheaded in sacrifice to our great archosaur overlords if I said any more.

Sometime after I got back from that trip I did these two drawings for an upcoming paper on Apatosaur combat I’m a coauthor on with Matt Wedel, Mike Taylor and Darren Naish.

I then finished a mixtape of new raps about fighting you with animals in the jungle called JUNGLECAT TECHNIQUE, and a new self produced album called Gather Bones. If you like my music, I hope you’ll consider supporting it on bandcamp.

wise men

Also at some point I did this reconstruction of an early Cretaceous angiosperm called Frenelopsis for Nathan Jud’s paper re-describing the taxa:

And I also did a bunch of drawings and concept art for Earth Beasts Awaken part 3, and a pile of sketches as rewards for my Patreon supporters, many of which can be seen in the photo galleries over on the historian facebook page
Cavern Glower

And now (like right now) I’m working on another illustrated sign for another Utah BLM dinosaur trackway site commissioned by ReBecca Hunt-Foster. I’m not going to share it right now though, because you have to support me on Patreon to see the behind the scenes stuff that isn’t finished yet, as well as special bonus content videos like this B-reel footage of the Snow Painter creature from Earth Beasts Awaken part 1 that I put together for my new Patreon supporters:

For those of you who have supported my work by buying art, making a donation or just sharing and hyping the hell out of it, thanks for the support!!!

Oh yeah, and I also put a ton of art up on my new Redbubble store, so you can even support my art by rockin’ it in the forms of various interdimensional style armors!!

Mill Canyon Dinosaur Trackway

As some of you know, I’ve been doing paleo art work in addition to finishing albums and developing the next Earth Beasts Awaken videos, and I’m excited to finally announce my most recently finished paleo project: an illustration of the Mill Canyon Dinosaur Trackway commissioned by Utah BLM Paleontologist Rebecca Hunt-Foster for an interperetive trail sign overlooking the dinosaur trackways near Moab Utah. Here it is on site.

The printed sign you see above is pretty big, 30″x36″ (about a square meter), and the tracks drawn in my illustration had to match the view from where the sign was placed. So the finished illustration had to be really really detailed. In addition to that, the trackway preserves a huge number of footprints from an awesome diversity of animals – at least ten different kinds of footprints and other traces are present – and ReBecca wanted me to depict as many of these animals as possible without making the composition seem to unnaturally crowded, as the animals weren’t likely all there at the same time. Oh, and just to make things extra difficult, basically no good skeletal fossils are known from the same strata as the footprints (the Ruby Ranch member of the Cedar Mountain Formation – Early Cretaceous), so the animals all had to be reconstructed based on close relatives and specimens known from strata a few million years older or younger. All in all this illustration represents my largest, most challenging illustration to date.

In order to reconstruct the panoramic view in my illustration so that it would match the real-life view from where the sign is now placed I had to go to Utah and photograph the site. So I drove out there and camped nearby, and visited the site multiple times a day for 3 days in order to figure out when the best time of day the sunlight was best for viewing the tracks. I found that sunrise was not only the best time to view the tracks, it was goddamn gorgeous and revealed details to me I would’ve never noticed other times of day when the light was higher. So I shot this panorama of the trackway at sunrise, and Rebecca and her husband John Foster (also a Paleontologist) and even their daughter Ruby paced out the best preserved tracks in front of the camera so I could later trace them over my panorama image, which is how I made trackway “field guide” that’s under the main illustration on the sign.

The other reason I was there was to try and make some sense of this intensely complex site and to try to figure out what, of all of it, would be the focus of my illustration. In the process of checking out the site I noticed so many awesome little details that I simply can’t write about it all here, so for now here’s a gallery of some of my favourite tracks:

But even after visiting the site, walking that ancient lakeshore, searching for details which might give a clue as to what was really going on there, I still found myself perplexed. What was this environment? Why were the tracks of a huge diversity of animals exquisitely preserved there, while no recognizeable plant fossils could be found anywhere nearby? What were all the big plant eaters eating? Fortunately renowned Paleontologists Dr. Jim Kirkland and Dr. Ken Carpenter offered me some great input, along with Elizabeth Montgomery, a graduate student working on the geochemistry of the ancient lake, and with their guidance the look of the lake and the surrounding landscape began to take shape. Ken and Jim explained most patiently to me that the tectonic activity in the area hadn’t yet produced any mountain ranges or big rock outcrops that would be visible in the background as they are in modern times, but the tectonics further west did play a role in forming the lake. It appears that the lake was in a foreland basin, which is basically the gradually sloping wash of sediments that forms behind a mountain range that’s being pushed up by tectonic activity.


The lake, it appears, was the lowest point for many miles around, and at around 20 miles in length was likely the largest body of permanent water in the area. The ancient sediments in the area indicate a fairly arid environment, perhaps something like the dry open savannah in modern east-central Africa, which might explain why animals were converging on the shore of the lake. Perhaps most interesting though, is that Elizabeth’s geochemical analysis indicates that the lake was likely semi-saline with a unique alkaline water chemistry that caused it to precipitate dolomite, which is basically dissolved limestone, and that combo of dolomites and clay and algae on the shore of the lake made for a particularly resilient concrete-like mud that baked in the desert sun as the lake’s water level dropped, then became harder than the surrounding stone when it was eventually buried in sand by a big flood. According to Elizabeth’s work, there are only two lakes today with a similar water chemistry to that ancient Dinosaur lake: Lake Changara in the altiplano of Chile, and Bosten Lake in China.

Both of these lakes have something really interesting ecologically going on. Despite being semi-saline, lots of animals visit the part of the lake where fresh water flows into it, because the fresh water pushes a lot of the salt and lime deeper into the lake. The fresh water and rich nutrients mixing also support a profusion of soft water plants and algae, which feed various animals (and which may not fossilize readily). Intriguingly, while tracing the layer of rock that forms the lake shore I got the distinct impression that there may have been an inflow channel just alongside the most concentrated area of dinosaur tracks and crocodile slides…

Could it have been that the animals were converging on the one spot where they could find fresh water and perhaps even some aquatic salad during the dry season? While we may never know every detail of this ancient lake’s ecology and geology, it’s nonetheless awesome to be able to visit a place where you can still see the very specific movements of individual animals that lived and died over a hundred million years before our time, recorded in the landscape before you. I strongly encourage any of you who might happen to visit Moab Utah to check out the Mill Canyon Dinosaur Trackway. I don’t think you’ll be dissapointed by all the work ReBecca and a handful of other paleoartists including Mark Witton and Jeffrey Martz and BLM staff put into the interperetive trail around the site, and if you’re tuned into the landscape and what it’s telling you, I gaurantee you’ll be blown away by some of the things you’ll see recorded in the mud of that ancient lakeshore…

#BuildaBetterFakeTheropod …WITH SCIENCE!

If you’ve been following me on twitter you’ll no doubt have found your feed infested with bizarre fictitious dinosaurs with the hashtag #BuildABetterFakeTheropod. The idea behind the hashtag was to try and come up with better, more scientifically inspired fake dinosaur designs than Jurassic World’s dated, unrealistic looking gray behemoth “Indominus rex.” Turns out, coming up with something more interesting and more science based isn’t very hard, because paleontologists have already done a ton of hard work over the last 20 years discovering and describing and educating the public about a diverse menagerie strange and wonderful lifeforms all of which suggests a world of speculative biology ripe for movie-monster exploitation. Over the course of the last few weeks I’ve posted a bunch of illustrations to my twitter and I thought I ought to explain some of the science that inspired a few of them in more than 140 characters.

“Cryptonychus arborealis” a semi arboreal Dromeosaur (“raptor”) from a tropical rain forest environment:


It’s apparently pretty hard to become a fossil. While some environments lend themselves to making fossils more than others, many environments aren’t so good at it, and some are really really bad at it. Tropical rainforests are one of those environments that can be really really bad at making fossils. Constant heat and humidity encourage an abundance of decomposers, and a thick mass of vegetation binds up all the available soil, so things rarely get buried in the mineral rich mud, sand or clay that help preserve remains. What that means is that there are vast swathes of some of the most bio-diverse ancient ecologies that we will never know anything about… That means LOTS of dinosaurs that just rotted and were forgotten. Forever. Now that doesn’t mean we can’t speculate about what might’ve been living in such environments, as many things from environments that were good at making fossils likely had relatives in environments that were not so good at making fossils (as many living things do today).

So, think of humans, or cheetahs. Both are widespread predators (well, cheetahs used to be widespread – once ranging throughout southern Europe, India & the Middle East) who evolved to hunt by chasing things down in an open Savannah environment. But both humans and cheetahs aren’t the only hunting primates or big cats around. We live at the same time as animals that share a common ancestor with us. In the tropical jungles of Africa there are both leopards and chimpanzees, both of which hunt in trees. Now, when I consider that the Velociraptor and Utahraptor that we know about hunted in open floodplains & semiarid woodland environments (good at makin fossils), and they share ancestry with smaller “raptor” dinos that appear to be arboreal (tree climbing) forms (some of which were likely gliders or fliers), I gotta wonder: were their weird big jungle raptors that hunted in way up trees?? My “Cryptonychus” (meaning “hidden claw”) is an attempt to come up with something like that. As it’s name (and hopefully the art) implies, it is a large ambush hunter, with a shaggy coat of feathers to camouflage it amongst the mossy vines an branches as it creeps slowly through the trees until if finds a perch near a game trail or nest. Then it waits… Silent. Motionless. Until the prey comes just… close… enough!

Giant Heron-like Ornithomimid

Ornithomimids are the group of Dinosaurs that looked sorta like ostriches but weren’t. The group includes Gallimimus, which was included (albeit featherless) in the first Jurassic Park movie and (even less accurately) in the new movie. Deinocheirus was a weird giant member of this group, and the recent discovery of more of its skeleton shows us that the ornithomimids could get BIG (like around T-rex big) and weird (it had a goddamn hump or sail or something)!

Deinocheirus figure from Natrure

One of the features that made it weird was that, unlike the rest of the (known) ornithomimids, Deinocheirus has a peculiar spoon shaped bill, likely for cropping plant matter or sifting nutritious crud out of the water like ducks do. The rest of the group has more pointed beaks, similar to that of modern generalist feeders like chickens and ostriches and the like. So, if this lineage of dinosaurs evolved a range of bills from sorta-pointy, to really-spoony, why not extra-pointy? It is not uncommon in evolutionary history to see groups of generalist feeders give rise to species or whole groups more specialized for feeding a certain way, which seems to be what Deinocheirus was doing. Perhaps somewhere, lurking in the depths of time, still waiting to be discovered or missed by fossilization completely, there were Ornithomimids adapted to spear and gulp down smaller animals as modern herons do… Oh, and by the way, herons are pretty closely related to spoonbills (they’re both Pelicaniformes).

Early Jurassic “Sinosaur-Line” Theropods


There is a big hole in the fossil record between the smaller late Triassic ceolophysoid theropods and the big giants (Like Allosaurus and Ceratosaurus) that appear in the fossil record in the middle Jurassic. The medium to large sized early Jurassic theropods that have been found (such as Dilophosaurus and Sinosaurus) are rare and many are highly fragmentary, yet they seem to indicate some interesting things were going on. Many of them have strange crests on their heads, and their overall body plan appears to be transitioning from a long and low body plan, to one with more robust legs, arms, heads and necks, likely for taking down larger prey. The creatures in the above drawing are my attempt to visualize a powerful-yet-speedy intermediate form, with ample strength to dispatch human-sized prey, but long powerful legs to chase down even off road vehicles. I, for one, would love to see a chase scene where a pair (or more!) of hungry theropods easily keep pace with a speeding off-road vehicle and the human prey within has to avoid being pulled from a broken window or opened top as the vehicle bounces and lurches in its struggle to navigate the rugged terrain, effortlessly handled by the ancient hunters.

If you like this kind of speculative monster design stuff let me know, & I hope you’ll share it aroundI. If people like it I’ll do another post on a few of my other #buildabetterfaketheropod designs.

If you’re gonna make up a dinosaur (or other prehistoric creature) for what is ostensibly a science-fiction movie, it should be spectacular visually, frighteningly foreign yet believable in it’s character and behavior, and it should be based at least loosely on the mountain of surprising and fascinating knowledge about dinosaur anatomy and behavior that scientists and artists around the world have worked tirelessly to discover and communicate over the last several decades. In light of a new Jurassic Park movie coming out that apparently disregards all of that study and discovery, (even with regards to the not-made-up dinosaurs it features) I started drawing made-up dinosaurs that I think would be cool to see in a movie and I’ve been posting them to my twitter feed with the hashtag #BuildABetterFakeTheropod. I’ve decided that for the next week I’m gonna put a new one up every day, in the hopes that people will be intrigued about actual dinosaur science in the process. At the end of the week I’ll throw up a full gallery with all of them.

To start us off, here’s a speculative long-horned relative of the Abelisaur Majungasaurus, dripping with blood from a recent battle, possibly with a rival male. His neck is a swollen mass of fat and connective tissue meant to protect him from the bites, thrusts and slashes of his opponents…

Longhorn Abelisaur

While that horn on it’s head might look a bit ridiculous, it’s only an exaggeration of a feature known from a real Theropod dinosaur, Majungasaurus. Check out the horn-like knob at the top of it’s skull, and bear in mind that the rough knobby bone tissue indicates that there was soft tissue (possibly horn) anchored firmly to it. Also, the particularly robust skull bones are typical of animals whose heads take a lot of impact, which has lead Paleontologists to speculate that Majungasuaurus, and other Abelisaurs such as Carnotaurus may have bashed their heads into things.

Witmer Lab Majungasaurus

Given that spectacular head crests are know from other theropod dinosaurs, it seems reasonable to speculate that long-horned forms may have existed, or that the horn tissue that rotted away greatly enlarged what we see in the bone. Also such features easily result from simple genetic modification by humans (such as selective breeding as in the case domestic livestock). Most importantly, IT WOULD BE AWESOME TO WATCH THEM BATTLE EACH OTHER, or other dinosaurs, or threaten humans with their territorial behavior in a well directed feature film (all of which would be completely in line with modern dinosaur science).

Or if you prefer completely made up mythological prehistoric monsters, only aesthetically inspired by actual paleontology, then there’s this:
