Ziggy204 Posted May 21, 2019 Author Share Posted May 21, 2019 It is not cement, it is a rock fragment. The hole and groove's were filled with dirt. On one end the rings are small with no etching on the grooves, the opposite side the rings are thicker and have etching squiggles. I have a video but it is too large.

ynot Posted May 21, 2019 Share Posted May 21, 2019 What is the size of this? My first thought is a crinoid columnal print. 4 Darwin said: " Man sprang from monkeys."

Once you know the ID of what you have you could search the internet to see what others value it at. I originally thought this looked man-made because the spacing and regularity of the frills are a little too perfect. Looking from the side, the hole looks like it is a perfect circle. Maybe someone else could give you a more definite ID. I don't know a ton about crinoids. It could be a crinoid column print. Good luck. Link to comment Share on other sites More sharing options...

Scylla Posted May 21, 2019 Share Posted May 21, 2019 My first thought is also crinoid, too big for blastoid I think (but I am not an expert) Link to comment Share on other sites More sharing options...

Rockwood Posted May 21, 2019 Share Posted May 21, 2019 Also known as a mold fossil of a crinoid stem. Ligaments often hold the columnals together long enough for them to be preserved this way. Link to comment Share on other sites More sharing options...
vellis Posted May 21, 2019 Share Posted May 21, 2019 Seriously though, pretty cool that a crinoid stem can do that, new one for me too. 2 Link to comment Share on other sites More sharing options...
Plax Posted May 21, 2019 Share Posted May 21, 2019 The Mahantango in the east (PA MD VA etc) has lots of crinoids preserved like this. I think it's unusual to see one this diameter though. Link to comment Share on other sites More sharing options...
