some x-rays of the observed animals.

🚨NEW STUDY DROP🚨 New enantiornithine bird is described as, Plumadraco bankoorum, based on a complete skeleton from the Jurassic Jiufotang Formation of Liaoning. It bore a pair of long rectrices on its tail the authors think it used for social interactions 🎨: Ville Sinkkonen

The Tenth Anniversary Edition of Dinosaurs: How They Lived and Evolved is out and on (some of) the shelves... tetzoo.com/blog/2026/5/25… #books #dinosaurs @NHM_London

New post, new old model that I didn't publish before, today Dreadnoughtus schrani, I can't really say much about it, I liked how it turned out compared to previous sauropods, however these animals definitely seem very strange to me lmao.

Vulcanodon

Two Shunosaurus moving through a misty rocky forest, with a massive adult leading while the juvenile follows close behind. Their vibrant reddish-purple colors and striped tails give them a striking appearance as they quietly explore the unknown together.

🚨NEW STUDY DROP🚨 A re-analysis of Spinosaur skull fossils has found osteological correlates for the salt gland in birds and marine iguanas. This helps provide more support for their near-marine lifestyles. It would've been weird if they didn't have this. 🎨: Andrea Cau

You guys all know how much I love my #spinosaurids; well great new paper is just out showing evidence that #Spinosaurus had salt glands like modern #seabirds! tandfonline.com/doi/full/10.10…

For today's post, an Edmontosaurus annectens I made a long time ago; you can tell by its overall shape, lol. It's mostly based on Dan Folkes diagram, thanks to @TPixel55 for helping me at the time.

Sauroposeidon proteles (skin by: @MartinosaurioXD )

Sinopterus dongi, a new pterosaur species with iridiscent pycnofibers ! I placed some on the crest, is speculative but it made sense to me (Timelapse on the comments )

@Ivytherium No, I wasn't inspired by anything for this render.

@Paco26862358 Is this based on that famous Wayne Barlowe piece?

Two Ceratosaurus resting as the sunset fades across the horizon, silently watching the unknown. Beneath the last light of the day and the vast prehistoric landscape, both predators remain like ancient shadows from a forgotten world.

One of my most popular articles is this one, on the Muscovy duck. I have no idea why. tetzoo.com/blog/2023/9/17… #ducks #birds #ornithology

🚨NEW STUDY DROP🚨 A new specimen of Sinopterus dongi is examined using Micro-XRF, SEM, FIB-SEM, EDS, ToF-SIMS. Melanosomes and their structures were observed, and they correlate to green to magenta iridescent coloration. Another huge step in paleo coloration! 🎨: Chaung Zhao

🚨NEW STUDY DROP🚨 Paper re-describes many of the specimens applied to the Pinacosaurus genus. New species, Pinacosaurus hilwitnorum, is named from specimens applied to P. grangeri. P. mephistocephalus is too distinct and put in a new genus, Eopinacosaurus. 🎨: @AndreyAtuchin

Question: How "bendy" was Tullimonstrum? I keep seeing them reconstructed in a squidlike position. Was something like this possible.
