We're just a biological speculation Sittin' here, vibratin' And we don't know what we're vibratin' about And the animal instinct in me Makes me wanna defend me It makes me want to live when it's time to die

@TyrantLzrdQueen can’t wait to name a rex species for Tanystropheus

"How will we know which T. rex is which? This will be confusing!" Very easy: one will be called T. rex, and the other will be called Tylosaurus :)

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 and WOW! The new Paleozoic exhibit is fantastic. Dinosaur for #fossilfriday tax. @NMMNHS_Paleo

@evornithology that dinosaur has butt fluff

I have seen an angel. We breathed the same air, if only for a moment.

I’ve been known to write notes to my three-year-old neighbor

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

to be fair, I reviewed the saurischian paper but didn’t know its status and the croc came out of left field

I did NOT have two new taxa from the @GhostRanchorg 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

@Paleo_Tykoski @PerotMuseum 🤘🏼💀🤘🏼

@NotThatMarsh @PerotMuseum Cool idea! Is this close enough?

Was in @PerotMuseum recently with only a few lights on. The dim light made it easier to see the deep recesses in each neural spine of the big Alamosaurus neck series, and showed off how wide each spine is. This would have been such a thick-necked animal in life! #FossilFriday

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
