I won’t apologize for being the guy who splits the discarded bone layer to find the tiny fish and reptile jaws. #fossilfriday #triassicpark 🧪🦖

you’re always a short wander away from amazing things at Petrified Forest National Park

published now in PEFO's peer-reviewed journal Lithodendron! Postosuchus Supernova #fossilfriday #triassicpark 🦖🧪 petrifiedforestfieldinstitute.org/lithodendron...

did anyone else put their backpack down right next to a 200,000,000 year old fish jaw today?

the node representing the population of the most recent common ancestor of Sauria is right here in Holbrook, AZ 🧪🦖

spending Sunday morning with these ladies

Printed a Revueltosaurus skull for some outreach this week. Once thought to be an early dinosaur, this friend is actually more closely related to crocs. Specimens from Petrified Forest NP were the first to determine this important discovery. #fossilfriday #triassicpark 🦖🧪

~2018 I checked a waterline trench for fossils in PEFO’s backcountry and noticed a bone layer that I marked with a screwdriver. Yesterday I revisited the site and found my screwdriver, where I had nearly unknowingly nailed an in-situ dinosaur femur! #fossilfriday #triassicpark 🧪🦖

Sometimes all you need is a small fragment of a fossil for an ID. This Desmatosuchus osteoderm preserves the anterior lamina and rough lateral margin unique to the aetosaur taxon. #fossilfriday #triassicpark 🦖🧪

stopped by to see the newly remodeled NMMNHS in Albuquerque and WOW! The new Paleozoic exhibit is fantastic. Dinosaur for #fossilfriday tax. 🦖🧪

Our new museum seasonal and I are going to have fun with this. #bonewars #fossilfriday 🦖🧪

I did NOT have two new taxa from the Coelophysis Quarry in my April bingo card.

I have the privilege of getting a routine colonoscopy next week for my #crohns so here’s a pile of #triassic coprolites from Petrified Forest. #fossilfriday #splashdown 🧪🦖

caring for temnospondyls: big and small, old and new 🧪🦖

the Eye of Sauron watching us survey for endangered cacti. #fossilfriday #triassicpark 🧪🦖

Excited to celebrate Salinas Pueblo Missions NM and their remarkable synapsid fossil tomorrow! Meet me at 11 at the Manzano Mountain Art Council for a talk on your cousins, the synapsids! #fossilfriday 🦖🧪

the densest object in the Known Universe is the head of a dog begging to share her dad’s dinner #peppertime

The Chinle Formation - come for the climbing ripples, stay for the reptile footprints. #FossilFriday #triassicpark 🧪🦖

Pepper is rightfully wondering why Marasuchus and Tanystropheus are in a scene together #theDinosaurs

Can I offer you a nice Desmatosuchus fragment in these trying times? #fossilfriday #triassicpark #alwayssunny 🦖🧪

Gutted to lose a friend and colleague, Dr. Hans Sues. I spent the afternoon in one of his happy places- The Triassic. 🍻 Trias über alles.

I wish I could repost from that other site.

who ordered the rocks on rye? #FossilFriday 🦖🧪

brandi carlile is a NATIONAL TREASURE

@timdemko.xyz did you see your shadow this morning?

throwback #fossilfriday to the “Gumby” phytosaur site: 2013 v 2026. 🧪🦖

poor Placerias can’t get no respect

Met with a local landowner this week to organize & outline a manuscript describing the INCREDIBLE variation of Triassic reptile teeth she has been collecting and curating from her property, will be accessioned at @NMMNHS. Check out those compound denticles! #fossilfriday 🦖🧪

I think I have a parasite #peppertime

imagine my HORROR that we’ve been misrepresenting the Norian/Rhaetian boundary in our home.

Fun day in the Lower Triassic with @timdemko.xyz and others!

Pepper LOVES this whole shutdown=daddy’s home thing

a pretty skull of the phytosaur Redondasaurus collected from the Navajo Nation and housed at @museumofnaz, on loan to PEFO #FossilFriday 🦖🧪

shut down

raise your hand if you’ve been raptured today

Y’all remember when “binders full of women” was a scandal? How quaint.

When you come across an old friend… #fossilfriday #dilophosaurus 🦖🧪

Tootsie-wootsies of Coelophysis from Ghost Ranch housed at the Museum of Northern Arizona. #FossilFriday #feetpics 🦖🧪

Proximal end of a shuvosaurid I found at Petrified Forest NP yesterday #FossilFriday 🦖🧪

sorry we only have right-legged chicken

how funny would it be if #Ozzy rises from the dead in three days because he’s actually been Jesus this whole time

This week I found a Chindesaurus femur head that attaches to a specimen collected 21 years ago… #fossilfriday 🦖🧪

Repping George Clinton digging up some funky fossils 🛸 #pfunk

#fossilfriday brings you an associated rauisuchid skull from Petrified Forest National Park. #triassicpark 🧪🦖

Celebrating the grand opening of the newest Arby’s in Winslow, AZ. Dressed for the occasion.

I’ve solved the problem of never having a scale bar on hand #FossilFriday #tattoo 🧪🦖

‪[1/n] New paper co-lead by @emmadnn.bsky.social‬ @macroecoevoale.bsky.social‬ and I: we combined fossil occurrences, biogeography and climate modelling to investigate the origins and early evolution of pterosaurs 🔗 www.nature.com/articles/s41...

A nice little Zamites leaf from a sandstone capping the Chinle Fm near St Johns, AZ. Is it Triassic or Cretaceous like it’s mapped? 🤔 #fossilfriday 🦖🧪
