And here the results from the Solnhofen #paleostream! This image depicts large parts of the terrestrial fauna of the Altmühltal Formation, the best understood part of the litographic limestone formations of Germany. There were several reasons for gong onto land despite...

A group of Dorygnathus use a Seirocrinus raft as a hunting ground for fish, when a big Eurhinosaurus suddenly breaches the surface.

This scene takes place in Germany during the Early Jurassic, around 180 million years ago.

Digital painting by Peter Nickolaus, 2025.

Foggy morning in Late Pleistocene Patagonia.

#Art #SciArt #artbyjulio
A scene depicting the Patagonian scrubland in the early morning, dotted with araucarias and framed by foggy mountains in the background. A pair of Macrauchenia, four guanacos and a patagonian mara are seen among the grass. A Megatherium walks by further away and a crested caracara flies over the scene.

A couple of Nebulasaurus taito enjoy a nighttime swim as they cross a lake in China during the Middle #Jurassic. 🦕🦕🏝️

(Just a regular lake, nothing to do with #dinosaur reproduction… 😏)

New at #Patreon: discussion of this scene of Sinosauropteryx waiting out a feeding Yutyrannus for carcass access. Or - hold on - are they waiting for their parent to feed them? Behold, the compsognathid identity dispute, now #paleoart flavoured! #sciart #dinosaurs

www.patreon.com/posts/132334...
Because I'm a lazy, lazy man, I'm copying text from the start of my Patreon post that describes this scene. If you want to read the rest of the discussion, you need to visit https://www.patreon.com/posts/132334586 (I may be lazy, but I'm not stupid. OK, not _that_ stupid.) "It's nighttime in Early Cretaceous China, in the part of the world that will eventually be recorded as the Yixian Formation. A light dusting of snow covers the winter ground, and only the coniferous trees retain their leaves. The light of a full moon spreads through the misty sky, obscuring distant mountains but illuminating a large dinosaurian predator, Yutyrannus. It is consuming the bloodied remains of a small dinosaur that, from the silhouette, looks to have been a Psittacosaurus. Quietly surrounding the carnivore is a group of eight smaller dinosaurs: compsognathids. Their small size, long, stripy brown tails and facial masks betray them as Sinosauropteryx. They appear to be congregating in the hope of getting access to the Psittacosaurus carcass, some peering around the larger dinosaur at a respectful distance to identify pilferable morsels. The Yutyrannus is ten times their length and towers above them: surely it's best to wait until it's finished? Unless... wait: are these Sinosauropteryx enterprising opportunists, patiently waiting for the larger predator to have their fill? Or are they juveniles waiting for their parent – a tyrannosauroid – to finish with the carcass before they can have access, or even for it to provision them with food? What the heck has actually been depicted here?"

Southern #Sweden during the late Cretaceous. A pair of pteranodontids trying to keep a healthy distance from an admittedly passive mosasaur. Meanwhile, the hesperornithids take a short break from foraging to catch some rays. #paleoart #sciart #scicomm #dinosaurs
A scene from Kristianstad in southern Sweden (the Kristianstad Basin) during the late Cretaceous.

A Once Green Antarctica
The sauropodomorph Glacialisaurus (known from very fragmentary remains) strolls through a dense assemblage of flora at the edge of a forest. The plants are meant to represent Otozamites and Clathropteris. The scene takes place in Early Jurassic Antarctica.

Diesel the Tyrannosaurus
Photo of a gouache painting depicting a Tyrannosaurus rex. His head takes up most of the page, and he's turned almost to face the camera, with his mouth slightly open. He is brown with some red areas.

Published today in Biological Reviews:

"New perspectives on body size and shape evolution in dinosaurs" - the biggest paper from my PhD (my favourite chapter, too).

doi.org/10.1111/brv....

Here's a thread outlining some of our key findings. (1/10)
Cover image promoting the new research paper "New perspectives on body size and shape evolution in dinosaurs", written by Matthew Dempsey, Samuel R. R. Cross, Susannah C. R. Maidment, John R. Hutchinson, and Karl T. Bates, and published in Biological Reviews. Image shows a 3D Tyrannosaurus rex skeleton enveloped in simple geometric hulls, accompanied by an artist's impression of T. rex in life.

Kleptoparasitism. Geosternternbergia, Nyctosaurus and Enchodus. Inspired by the book Oceans of Kansas by Micheal J Everhart and the brown pelicans, magnificent frigate birds and delicious mahi-mahi tacos at my trip to Puerto Vallarta. #paleoart #pterosaurs
A chaotic scene of pterosaurs. A Geosternbergia with an Enchodus in its mouth is absolutely pestered by a flock of Nyctosaurus all trying to steal the fish.

Ok, another Mexidracon thread because I find this critter just fascinating.
In our latest stream I tried to illustrate my point further by showing the proposed sediment probing behavior I assume for this animal.
