Is that a brontothere ceratopsian?

Wow! Makes me want to see more mythological art from you.

I bet this is for the chapter about the elephant-skull hypothesis

Makes me wonder if Elon Musk was involved

I find it weird that Greg Paul isn’t cited anywhere in this paper. He’s the first one that comes to my mind any time a paravian group is proposed to be neoflightless avialans.

Phylogenetic relationships of Unenlagiidae among Paraves (Dinosauria) In recent years, several studies on the osteology, myology and palaeobiology of southern paravians of the clade Unenlagiidae have considerably increased the information on the group. Nevertheless, ...

So there is this new paper which shows that unenlagiids were actually secondarily flightless #avialans. Which is cool and all, though what confuses me is that Greg Paul isn’t cited anywhere in it, despite him being the first and strongest supporter of this idea: www.tandfonline.com/doi/full/10....

Cool!

Is this based on that one real life enantiornithean theorized to have had an extendable tongue? I forgot its name.

Diplodocus, reconstructed as an ocean-bottom dweller “grazing” on marine worms

Martin Wilfarth was a German researcher who in the 1940s claimed that Mesozoic Earth was experiencing super tides and that all dinosaurs were actually semi-marine animals. In a 3-part series I try to explore the how and why of his reasoning: www.manospondylus.com/2025/08/wilf...

All the #fossils I collected in Donkey Kong Bananza

Just finished the game and they absolutely nailed it. They made some pretty awesome remixes of your tracks.

So were these structures “solid” to the touch like leaves or actually fuzzy like feathers?

Do you think this means other drepanosaurs (like Megalancosaurus and Hypuronector) could have also had these “feather-scales”?

Speculative reconstruction of the dinosaur Corythosaurus with a fleshy trunk extending from its bony headcrest, used as a snorkel while the animal is submerged in water.

A teaser for a blogpost I am working on. Between the 1930s and 50s, German paleontologist Martin Wilfarth proposed that the headcrests on #hadrosaurs were actually attachment-points for snorkel-trunks. This was part of his wider ides that all #dinosaurs were tidal animals.

I think it’s beautiful

I noticed that I use “Yeah” way too often when responding to people I agree with. It’s getting repetitive. So instead I will use “Aye”, because then I can at least pretend to be a pirate while talking to someone.

Ah yes, the cake crab

Beautiful. Is that a large cloud formation on the lower left?

While you don‘t often see it in paleoart, there is decent biomechanical evidence that #glyptodonts were actually quite good at bipedalism. Here‘s a cute illustration from: onlinelibrary.wiley.com/doi/abs/10.1...

Reminds me of the cartoon plesiosaur woman I drew once
