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

Purple bones belonging to the pelvis of a Triassic reptile

During my first summer as an intern we collected its pelvis, described here: onlinelibrary.wiley.com/doi/full/10....

Gumby’s skull was collected in 2008 and is on exhibit at PEFO’s Rainbow Forest Museum.

ouchy arthritis!

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!

After a few weeks of prep, individual bones are being isolated! Here is a premaxilla and maxilla. #fossilfriday #TriassicPark 🦖🧪

Nope

shut down

raise your hand if you’ve been raptured today

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

Four park rangers pull a heavy white plaster jacket

Rangers gently guide the jacket on a sled down a steep hill

The field jacket in the back of a truck with the bones drawn over the top.

Well the wheels snapped off… but we hauled it 800 ft horizontally and 80 ft vertically down to a UTV this morning. #fossilfriday🦖🧪

These are to 50 psi

Bonus Martian rover vibes

The 300 lb jacket on four wheels

Has anyone tried this before? It actually rolls around pretty easily! Now we need to roll it 800 feet over to the cliff and gently lower it down 80 feet to a UTV. #FossilFriday 🧪🦖

sorry we only have right-legged chicken

Flip, Flip, Flipadelphia

Lower jaw bone with two teeth

Marshmallow-like white field jacket

Pulled the dentary out in its own jacket but the skull block is HUGE now… #fossilfriday 🧪🦖

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