Mirasaura

New paper alert! (My first!) This is a benchmark paper on all NPS fossils within the State of Utah through 2024. Loads of illustrations by me and pic by coauthors and collaborators. Open access, free to download! Thanks to all who made this possible! giw.utahgeology.org/giw/index.ph...

Very excited to share my exploration of the phylogenetics of early ray-finned fishes, out today in the Anatomical Record! Really busy day but I’ll have more info shortly. anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

New Triassic discovery! Researchers describe Fabanychus monos, new drepanosauromorph from Upper Chinle Formation (~214 Ma), AZ. Study of claw (ungual) anatomy via CT + histology reveals distinct morphotypes tied to ecology & taxonomy Sodano et al: anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Drepanosaurs are great. We've got Turdhands, Claw Claw, and Beans, and they all looked kinda like this:

It’s finally out! Our work addressing the origins of reptiles is published in PCJ! peercommunityjournal.org/articles/10.... We use novel info gleaned from the scan data of dozens of stem reptiles to substantially revise our understanding of early reptile evolution #paleontology #herpetology

New study reveals surprising jaw diversity in early ray-finned fishes (Actinopterygii)! Using XCT, researchers analyzed mandibles of 19 Devonian species—showing considerable variation in size, structure, and teeth.

I will never NOT be amazed by 3D tanystropheid or azhdarchid cervicals 😮 bioone.org/journals/Pal...

Weird dude update

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! #paleoart #art

Some bugs from the field! A white lined sphinx moth, a robber fly (with a meal), and a silverfish!

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

I am proud and grateful to present a dream project today in @nature.com www.nature.com/articles/s41... Meet #Mirasaura grauvogeli, a #wonderreptilewith skin appendages that rival feathers and hairs, challenging our view of reptile #evolution🪶🦎

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 #paleoart

Gulf fritillaries were out in droves today! I saw a ton of the little guys crawling on the sidewalk and the parking lot. The spines might look dangerous but they actually can’t sting.

Lost in the sauce (moss). The result of a tunneling adventure

Almost gave myself a heart attack when I didn’t see Raptor in his usual sleeping spot under his big hide. I forgot that I dug a pit under his log when I cleaned his tank so he curl up without his tail sticking out. Also didn’t remember I took a pic of him sleeping there earlier. Disaster averted

🚨🚨PhD position alert!🚨🚨 Do you like 🐢🐢? Or ecomorph evolution? I am offering a 36-month PhD position funded by the DFG about ecomorphology and neuroanatomy of turtles. Check out the ad here: www.senckenberg.de/en/career/sc... Please share and if you have questions, send me a message 😉

Found a friend (gulf fritillary) on the asphalt, hopefully it was just looking for a place to pupate and not hungry since I couldn’t find any passionflower vines nearby.

Got some great deals on some cool books at the LA Times Festival of Books today. I had to store the rest of the books I picked up in a friend’s office so my arm didn’t fall off on the way home haha.

I felt that earthquake all the way out here in LA, y’all alright over there San Diego?

Tree space and a new ray-finned fish out today! We delve into how methods to visualize the forest of phylogenetic tree space can be used to address the rogue taxon problem. Shout out to my co-authors and advisors Michelle Stocker and Michael Gottfried. ssbbulletin.org/index.php/bs...

Spent the day at La Brea tar pits with some friends and also some of the coolest animals that ever lived.

Woe, Djadochta fauna be upon ye! Some old (2022) sketches of dinos I never got around to finishing. #paleoart
