The preparation on this specimen was amazing. There are small spines where the arms branch that are usually blown off during inpatient prep. The delicate pinnules were also prepped with care.

@clarkeocrinus.bsky.socialArthroacantha carpenteri is one of the most common crinoids from the Devonian Silica Shale. This is a nice example of the calyx and parts of the arms that filtered the water for food. The gold tint is from pyrite or Fool's gold.
@quakeandquiver.bsky.socialA Smilodon skull for #FossilFriday #sciart
@clarkeocrinus.bsky.socialThis is a special specimen in my collection. I found it in a gravel road when I was a kid. It was the first fossil I was able to identify using my Audubon Society book.
It's not rare. I've found hundreds of Mucrospirifers over the years. I still have this one though.
@thammerich.bsky.socialSome 180 million years ago, this ammonite was swimming in the Jurassic sea.
Today, it sits quietly on a wooden table. Apparently, this is what happens when you get dug up and meet a geologist. 🐚🦕 ⛏🤠

@markwitton.bsky.socialNew #paleoart for #FossilFriday: Baryonyx walkeri portrait factoring new epidermal correlate data gathered for an ongoing project. "Yes" to lips, "no" to a cornified sheath on the nasal crest, "yes" to a boss and scale above the eyes. More details at my Patreon: www.patreon.com/markwitton
@coastalpaleo.bsky.social#fossilfriday Skull of the early whale Dorudon atrox from the late Eocene of Fayum, Egypt (Wadi al Hitan). Cast on display at the Canadian Museum of Nature; photo from the 2006 SVP meeting. #whaleontology 🦖🐬🧪
@witmerlab.bsky.social#FossilFriday Had a packed house the other night for a lab tour for the @ohiouniversity.bsky.social Geology Club. Over 2 hours of great questions & lotsa laughs! Thanks to Evan Doles & Abbie Fausnaugh for the photos! 🦖🦕🐊

@risky-on-rocks.bsky.socialI've been trying to get back in the habit of stretching my #sciart muscles with regular #FossilFriday drawings; I'm still agog over these trilobites with the massive eye towers that I drew/learned about last week
@stardusttostarfish.bsky.socialHappy #FossilFriday!
Two spines from an unknown fossil echinoid (Archaeocidaris or Miocidaris), Permian, north-central Texas.
Good examples of pre-Mesozoic Marine Revolution arms race in sea urchins.
Small squares are mm scale; large squares are cm scale.

@friedmanlab.bsky.socialA new addition to the UMMNH paleo gallery for #FossilFriday: the Devonian stromatoporoid Stromatoporella (UMMP IP 80674). These calcareous sponges were important reef builders before they went extinct at the end of the Devonian.
@deadbovids.bsky.social10,000 year old Warthog molar from Kenya for #FossilFriday
@sjbpaleo.bsky.socialThe Menefee Formation is known for fragmentary fossils, so durable taxa like turtles, crocodyliforms, and nodosaurs dominate the record. Our new material includes Invictarx distal spikes that project from the body wall and stiffen the edge of the dermal armor.

@ashpoust.bsky.socialGood #FossilFriday post - coughDinohyuscough is an amazing animal.
Honestly, I think it's as frightening as T. rex.
@corvuserpens.bsky.socialThis #fossilfriday I give you a paleoart piece I did recently for the PaleoPT congress about the Vandelli Skulls - 4 whale skulls discovered in the Adiça beach in Almada, Lisbon in the 19th century. Above is Adicetus vandelli and A. latus, bottom is Cephalotropis nectus.
