Two juvenile giant moa (Dinornis robustus) run energetically along a beach, creating some splashes as they go. Small waves roll in behind them.

Evolutionary Arms Race

Platecarpus tympaniticus chasing a small school of Pentanogmius through the waves of Western North America, 82 million years ago. Accompanying the chase is a group of ammonites, Baculites, with one individual being unable to go with the flow, thus being swept by the waves. Where people of modern day surf the waves of Southern California, it could be possible for shallow water mosasaurs like platecarpus to surf the waves in an area of what will one day become the dry plains of Kansas.

BREAKING: President Trump signed an executive order directing states to criminalize and institutionalize people experiencing homelessness, addiction, and mental health disabilities.

during a foggy morning, two adult Argentinosaurus travel through the thick clouds, one is only barely visible and both have the upper portion of their necks and lower portion of their bodies obscured. they tower over the trees closer to the camera, a carcharodontosaur looks up at the towering giants. Argentinosaurus is a kind of sauropod dinosaur (typically long necked and usually large quadrupedal reptiles), it's one of a handful of species that are debated to be the largest dinosaur in both size and weight however due to fragmentary material the debate still rages on

an adult Wulong is hunting on the wing, it's about to use its right leg to kick a juvenile Sinopterus out of the air. Wulong is a kind of microraptorine dromaeosaurid (bird-like theropod dinosaurs who were capable of gliding and in some instances powered flight). it's only known from a juvenile specimen but we have preserved feathers from it that show the individual had iridescent feathers on the forelimbs and hindlimbs, with grey feathers on the rest of the body. Here i speculate that the colouration was a juvenile colouration and that the adults would be visually distinct Sinopterus is a kind of tapejarid pterosaur (flying reptiles that were frugivorous and had large conspicuous crests) known from the same formation as Wulong, ive based this reconstruction on the dubious pterosaur Nemicolopterus that many - includng myself - consider a juvenile tapejarid

a Dorudon swims by the camera with the corpse of an Eopelecanus in its mouth, however most of the Eopelecanus' body is obscured. the Dorudon's body is covered in scars Dorudon is a kind of basilosaurid whale (ancient whales that still had small backflippers) which was predatory and looked not too disimilar to modern cetaceans (other then its visible hindlimbs) Eopelecanus is the oldest recorded pelican, despite the fact that it's only known from a single tibiotarsus (a bird foot bone), we know that pelicans have been very conservative in their morphology throughout their evolution so it's within reason to reconstruct it broadly similarly to modern pelicans

a Temnodontosaurus surfaces for a breath, its body is covered in scars from previous battles and lamprey bite marks Temnodontosaurus is a kind of large predatory ichthyosaur (ichthyosaurs are a large group of whale-like marine reptiles that lacked scales, were warm-blooded, gave birth to live young, and had thick layers of blubber among other adaptations to live entirely in the water). studies of its head anatomy show it would've had great vision and a great sense of smell, while stomach contents show it fed on mainly cephalopods like squid, but also fed on other ichthyosaurs like the contemporary Stenopterygius of which we have 3 juveniles preserved inside stomach contents. a recent study of its fins showed that it had novel spike structures on the trailing edge of its flippers and creases on the surface that reduced the noise produced when swimming like those on owl wing feathers aiding the theory that it was an ambush predator.

after a brief hiatus cause Josch was at EAVP, #Paleostream flocking is back!

this week we sketched Argentinosaurus, Wulong (mine is hunting a juvenile Sinopterus), Dorudon (mine is eating an Eopelecanus), and Temnodontosaurus

Happy #PortfolioDay!
I'm a palaeontology student and mostly draw various unusual animals (both extinct and extant), and like doing interesting vegetation and backgrounds! I also do some more technical scientific illustration.

Concept art of baby Spinosaurus for the upcoming NBC Universal docuseries Surviving Earth

Ok… so the cat is out of the bag and I can FINALLY start talking about this. I just confirmed with Tim I can say that I did a lot of concept art, like this baby Spinosaurus, for the new docuseries #SurvivingEarth coming out in 2026!

So excited for you guys to see this!

The freakiest marmoset to ever exist

Carnotaurus on a windy night.

Two digital sketches on one page, 20-30 min each (i worked on them just a little after the stream) Top: a stormy scene, the sea is calm for now, there's no waves, but a big storm is coming. You can see how dark it is under the heavy cloud, some leaves flying past the camera as the storm rushes the wind forward... But the leaves aren't the only thing that is flying past... And unfortunately, this thing is not even flying. A dark colored pterosaur Zhejiangopterus (that might just be as tall as you) just... stands there, looking at you, beak forward, not even blinking. It doesn't care about the storm behind. You have a few seconds to decide what to do. Bottom: something to change the mood! A quite peaceful scene, nice golden clouds against the blue sky, and a big lizard Bolg amondol flicking it's slightly blue tongue. The creature itself is grey, with some yellow markings on the head and neck. No ill intentions unlike the creature in the first sketch, i'd say.

Two digital colored sketches on one page, 20-30 minutes each. Top: Diplobune at night, probably in the trees (as you can see a couple of branches close to the camera), illuminated by the bright moon behind it. It's very fluffy. Probably very soft to touch too. The creature is kinda deer/kangaroo looking, mostly brown, with some white spots around the eyes, on the neck, and the fur in the ears. Bottom: A holy Iberomesornis. Not literally, but it's flying up in front of a cloud and some iridescence above it, so it looks quite holy if you ask me. Nonetheless, Iberomesornis was a small Cretaceous bird that could fit in your hand. On this drawing it's quite dark, illuminated from behind, but it has quite a few dark spots on the wings.

The latest #paleostream flocking! I just wanted to draw clouds. The next personal theme is a secret 👀

Zhejiangopterus, Bolg amondol, Diplobune, Iberomesornis. More info in alt as always!

A lone Diplobune minor peers down from the canopy, its slumber disturbed by a light shining from the ground below. Around it flutter a swarm of moths and other nocturnal insects, gathering in the new light source.

CRACK!

Razanandrongobe easily crushes a dinosaur's femur to feed from its nutritious marrow

If Barinasuchus' skull rivaled the size of a Daspletosaurus, this crocodyliform's skull rivaled the size of a T. rex, and was arguably more specialized for bone-cracking

Case in point:

an allosaurus and ceratosaurus are seen macking it in a cartoonish style, with excessive drool and green mystery discharge oozing from their mouths.

@tessasaurus.bsky.social hi tessa, some friends made me aware of your theropod kissing artwork, I would like to share mine of the same format.

The allosaurus loves what it wants.

The Mr Beast Biopic has been indefinitely postponed after a group of large apes on set mistook Jimmy "Mr Beast" Donaldson's iconic and charming smile as a sign of aggression and tore him into little pieces like tissue paper.

He is expected to make a full recovery.

A very speculative depiction of a Koreaceratops hwaseongensis laying under some shade. Koreaceratops is an early ceratopsian dinosaur known from the partial remains of its tail, hip, and hindlimbs. The front half of the animal is unknown.

Happy 26th anniversary to #SpongeBob! Had to do another season poster for this occasion #art

ICE can enter anyone’s home, and abduct and deport them to a foreign prison indefinitely because the DOJ says they can ignore the 4th, 5th and 15th amendments.

If there’s no due process or protections against illegal search and seizures, none of us are safe.

Nearly forgot to post this!
After Bear Gulch I actually worked on a second sketch yesterday on #paleostream!
