Nuna Posted October 23, 2019 Share Posted October 23, 2019 Found this at Ladonia Fossil Park. Thought it was just a phosphate nodule but I've recently seen similar fossils labeled as fish coprolite. ID assistance would be appreciated, thank you for your time. 2 Link to comment Share on other sites More sharing options...
sharkdoctor Posted October 23, 2019 Share Posted October 23, 2019 The laminations in photos 1 and 3 look very much like the shark coprolite (or other fish with a weak spiral valve in their gut) we find on the east coast. Here, I would suspect this sort of piece would be the result of lagging or reworking at some point in the past. Some of the outer layer get removed, showing the inner portions of the coprolite with all of its intricate folds. 3 Link to comment Share on other sites More sharing options...

Would this coprolite indicate the size of the fish or shark, even with lost layers? Is the coprolite itself average in size? 1 Link to comment Share on other sites More sharing options...
Carl Posted October 23, 2019 Share Posted October 23, 2019 This gets a pretty high rating as a probably coprolite based on shape alone. Very likely a spiral form. The material looks a bit less ideal as a match but that shape is pretty strong. 1 Link to comment Share on other sites More sharing options...

GeschWhat Posted October 26, 2019 Share Posted October 26, 2019 I agree with @Carl (as usual). It looks to have a spiral shape or possibly folded as described on the Virginia coprolite poster? 2 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
