Grad student and aspiring paleontologist, or as I like to call it a nerd with too many opinions on fossil sand dollars (I'm told I do a great impression of one). I don't post much these days. Also like reading and making pixel art. She/they bi and Catholic

Working on invertebrate #paleoart at the moment, knowing I'm probably making mistakes despite best efforts, consulting primary literature etc. Inverts are much like fossil plants: there are few accessible resources on their appearance so we must wing it, or go down deep rabbit holes to restore them.

Please, if you've ever wanted to help me financially, help PRI. They're an independent museum in Ithaca at immediate risk of foreclosure. I would be so crushed if they didn't make it.
Well it seems it is going to be to late for @lastweektonight.com to help with their hiatus. Any suggestions for a big sci com/science interested news account I should play with to help save PRI?
Tag them in the comments with your pitch for why they should help out this museum maybe

This is a late Cretaceous echinoid, Hardournia mortonis, from the Peedee Fm. near Holden Beach, NC. The mouth structure is preserved with 5 beak-like teeth called Aristotle's lantern.

Lovely plate patterns from this isocrinid stalked crinoid- NOT a fossil but dang! sure looks like a "living fossil"!! Skeletons are calcium carbonate. #echinoday

Less rain, and less ice, means fewer fossils to find. And more wildfires that can keep paleontologists away from field sites. How decades of western drought are changing paleontology, my latest for SIERRA. 🧪

The goal of conservation should not be to return the world to primeval depopulated wilderness but to build and maintain sustainable relationships with the world.
Do you have any extremely niche, but serious, ethical stances?

As of today, my master's thesis has officially been signed and submitted! Morphometric Assessment of the Cenozoic Echinoid Genus Astrodapsis should be available through the CSU ScholarWorks repository soon, if weird miocene sand dollars are a thing you're interested in.

Many mammals across the world have evolved an otter-like body shape and lifestyle. Perhaps the oddest and one of the most obscure is the West African giant otter shrew (Potamogale velox).
Not an otter, not a shrew, but a distant cousin of elephants!

Thanks, I feel inspired:
While trees rake carbon from the sky

eventually that heat's released
by fire or rot or gnawing beast.
But if you've got the clime to suit,
and want to see less top, more root
while storing carbon out the ass
you cannot beat a prairie grass.
