Jan Lester Posted November 6, 2022 Share Posted November 6, 2022 Unfortunately I don’t have any provenance for this rock. I bought it years ago screwed to a piece of driftwood for my fish tank. When the driftwood had withered away to a twig, I was throwing it away, but noticed the fossil traces on the rock and kept it. Came across it a few weeks ago, and started messing with it. The fish store was local, and I would assume that this was created by a somewhat local person (in east TN), but I don’t know. The top of the “calyx” is translucent from the underside. Not the softest limestone I’ve found…I can see signs of bryozoans and brachiopods, but it’s hard to expose them. Link to comment Share on other sites More sharing options...
Rockwood Posted November 6, 2022 Share Posted November 6, 2022 Is the fourth photo down the opposite side of what is shown in the first ones ? Link to comment Share on other sites More sharing options...
Jan Lester Posted November 7, 2022 Author Share Posted November 7, 2022 Yes, the “underside” of the rock. Sorry, I should have noted that. Link to comment Share on other sites More sharing options...
Rockwood Posted November 7, 2022 Share Posted November 7, 2022 I can't really see any definite indications that this is a calyx, but it sure seems possible. Link to comment Share on other sites More sharing options...
Jan Lester Posted November 8, 2022 Author Share Posted November 8, 2022 Thanks! I actually was thinking coral head, before a grad student who saw a pic said many calyxes (sp?) were geodes. Also the proximity of crinoid pieces seems suggestive. I want the “lines” nearby to be a crinoid head, but my son says bryozoan. Either way it’s cool.
