Al Dente Posted July 25, 2020 Share Posted July 25, 2020 Do you see parallel layers on the edges? If so, it might be a piece of crab shell. 1 Link to comment Share on other sites More sharing options...

Boesse Posted July 26, 2020 Share Posted July 26, 2020 Just throwing this in here: boxfish ostederms, or at least supposed boxfish (Ostraciidae) osteoderm plates from the Paleocene of South Carolina look quite a bit like this. [but: they might not be identified correctly] 2 Link to comment Share on other sites More sharing options...

Kolya Posted August 3, 2020 Author Share Posted August 3, 2020 Can it be some part of plant? Two more detailed photos: Link to comment Share on other sites More sharing options...
Boesse Posted August 3, 2020 Share Posted August 3, 2020 There's not many of these that have been published with good images - on the left are Paleocene ostraciid ossicles from SC and on the right is an unpublished specimen in a private collection, but which I have no doubt is identified properly - Pungo River Fm., Lee Creek Mine - from elasmo.com. 2 Link to comment Share on other sites More sharing options...

Thanks a lot! But what are the small perforations (You can see on the more detailed photos in the last massage)? Link to comment Share on other sites More sharing options...
Boesse Posted August 3, 2020 Share Posted August 3, 2020 No idea! It's unclear if the Paleocene specimens are actually from ostraciids or not. There are very few papers out there on modern or extinct ostraciid osteology. There are often more questions than answers with these sorts of weird specimens. 1 Link to comment Share on other sites More sharing options...

Mahnmut Posted August 4, 2020 Share Posted August 4, 2020 No idea, but the last pictures show a lot of fine structure that may help? 1 Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...
