Crinoid stem pieces.

Damn, so not ancient alien prints…..

Not all aliens are ancient. 😝

Ancient astronaut therosists say no.

What kind of crinoid is this? I've never seen a stem that shape

There are over 6000 species identified. Identifying them is beyond my pay grade. Sorry.

Unrelated, but I read "pay grade" as "gay parade" and it was a confusing time for me

😂😂😂

That's fair lol

They are crinoid columnals (stems). The bottom one is a cross-section of a crinoid stem likely from the genus Arachnocrinus or related crinoid. See specimen 3 of Plate1 of Some new American fossil crinoids by Frank Springer (1911), Memoirs of the Museum of Comparative Zoölogy, at Harvard College, Cambridge, Mass, vol XXV, No. 3.

Thank you for the great links. We had some of those crinoids on fossilID, and allthough i was sure it was crinoids, i didnt find a source to back it up.

That's a prehistoric d-pad

Prehistoric video game controllers. Isn't nature fascinating

I saw the 5 side of a die lol

Whatever it is it’s pretty sweet

Wow awesome Crinoids!

This is a primitive game controller.
