I found this beauty in Bardstown KY. The rock feels so smooth and unlike many others I have found with Crinoids and such in them. Do you all have any idea of what this may contain?
It seems to be marine/reef debris, within which I can see two major components. There are lots of ribbed/ridged structures like this, which are the remnants of brachiopod shells:
And lots of twig-like structures like this, which will either be branched corals or bryozoans, or possibly a mixture of the two:
Thank you very much for your replies. I absolutely love finding fossils. Thank you Red-Coat for helping me identify some of what was deposited in this fossil.
