Hello, my name is Megan and I'm a PhD student at USC studying tetrapod claws! I'm a big fan of paleoart, sci-comm, and anything Triassic.
The upper body of a long speckled Funcusvermis gilmorei, an amphibian related to modern-day Caecilians. It is crawling across moss with scattered ginkgo leaves nearby A pop art depiction of an orange Drepanosaurus unguicaudatus on a black background. This animal has a humpback shoulder, large arm claws, and a winding tail tipped with a claw. In the bottom right corner are horsetails and a lacewing. There are orange stars scattered in the background. A tan Dimetrodon is walking across a plain off-white background. It has a large head, thick neck, small legs, and a tall sail that extends past the border of the image. Two white resin casts of Drepanosaurus claws are held in a hand. Each is slightly larger in size than one of the phalanges of the person that is holding them.

New records of diverse small reptiles with thecodont implantation from the Carboniferous–Permian Halgaito Formation (Cutler Group) of southeastern Utah, U.S.A.
Carboniferous–Permian (C–P) amniotes and stem-amniotes were historically well documented in the southwestern U.S.A., but Carboniferous reptile diversity and abundance was relatively low compared wi...

New phylogenetic work unifies fossil and living ray-finned fishes using anatomical ontologies, revealing clearer origins of Actinopterygii. Analyses refine the positions of key Paleozoic–Mesozoic groups.

New research on juvenile Redondasaurus fossils from Chinle Fm. reveals that immature phytosaurs show a mosaic of traits seen in both early and late-diverging species. Links b/w growth & morphological evolution in Phytosauria.

Drepanosaurs are great. We've got Turdhands, Claw Claw, and Beans, and they all looked kinda like this:
Paleoart of Drepanosaurus. It vaguely resembles a chameleon, but it has a birdlike beaked head, a massive claw on the second finger, a hump on its back, and a claw at the end of its thick tail. It is depicted hanging from a branch, with a striking green, orange, and cyan color scheme. By Scott Reid

Could extraordinary plume-like structures like those on Longisquama and the recently described Mirasaura be present in other drepanosauromorphs? I think it is not completely out of the question!

Look at this perfect Triassic friend. Mirasaura was a "monkey lizard" with a prominent sail on its back that wasn't really like scales or feathers. Studying these fossils also revealed that the enigma Longisquama is a drepanosaur with a fan, too. I'll tell you more at @smithsonianmag.bsky.social

Here it is! Please welcome the AMAZING Mirasaura grauvogeli, a NEW MARVELOUS Drepanosaur published in NATURE today!
This astonishing reptile lived during the Middle Triassic in Europe and it possessed an amazing crest made of plume-like structures!

I was commissioned to bring it to life
