Mochaccino Posted August 31, 2022 Share Posted August 31, 2022 (edited) Hello, I came across this listing with no ID/locality info and poor photos, can anyone identify at least what it is? About 5 cm across. From what I can barely make out it has some symmetry and regularity in structure/patterning so I think it is indeed a fossil, perhaps a cystoid theca or crinoid calyx or even float bulb?

Mochaccino Posted September 1, 2022 Author Share Posted September 1, 2022 Got some better photos and a locality info from the seller, apparently it was collected from coastal North Carolina. Might be some sort of coral or bryozoan? Link to comment Share on other sites More sharing options...
DPS Ammonite Posted September 1, 2022 Share Posted September 1, 2022 (edited) Bryozoan since the openings are so small. Edited September 1, 2022 by DPS Ammonite 1 1 My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

I had to look pretty hard to see them after reading DPS's post, but found them in that photo. Of course, Tim's enlargement . . . . Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
Rockwood Posted September 1, 2022 Share Posted September 1, 2022 There may well be bryozoans there, but that's not a bryozoan colony. Link to comment Share on other sites More sharing options...

One of the encrusting bryozoans looks like it covered something round and bumpy. What do we know of the age? Link to comment Share on other sites More sharing options...
Al Dente Posted September 1, 2022 Share Posted September 1, 2022 The Eocene Castle Hayne Formation has similar domal colonies. This one is from the NC Fossil Club publication on invertebrates. The scale bar is centimeters. I've collected larger ones. 5 Link to comment Share on other sites More sharing options...

The one in my photos has a tapering base instead of being a perfect dome like yours, but otherwise the general appearance seems to check out.

I'm pretty ignorant regarding bryozoans; is the sort of cracking/flaking in this specimen atypical? It does seem like there is an outermost shell-like layer cracking, and something underneath? 1 Link to comment Share on other sites More sharing options...
