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

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

[Adam Marsh @NotThatMarsh]

fragmentary as it is, skeletal material of these beasts are seemingly rare in the Upper Triassic of North America

published now in PEFO's peer-reviewed journal Lithodendron! Postosuchus Supernova #fossilfriday #triassicpark https://t.co/5NmR0wZhBI

@VTechmeetsPaleo left us a fun puzzle and challenge: a rauisuchid maxilla eroding out of a sheer cliff 35’ in the air… (nobody tell OSHA, yet)… #fossilfriday

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

[Adam Marsh @NotThatMarsh]

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

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

[Adam Marsh @NotThatMarsh]

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

[Adam Marsh @NotThatMarsh]

stopped by to see the newly remodeled @NMMNHS and WOW! The new Paleozoic exhibit is fantastic. Dinosaur for #fossilfriday tax. @NMMNHS_Paleo

[Adam Marsh @NotThatMarsh]

@evornithology that dinosaur has butt fluff

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

[Adam Marsh @NotThatMarsh]

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

[Adam Marsh @NotThatMarsh]

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

[Adam Marsh @NotThatMarsh]

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
