GABRIEL.P Posted January 29, 2021 Share Posted January 29, 2021 This fossil comes from Richards Spur and it is Permian. I think it's a coprolite with a bone bitten by the predator that the coprolite belongs to, but I'm not very sure. What do you think about it? Thank you.

sharkdoctor Posted January 29, 2021 Share Posted January 29, 2021 I'm not seeing anything I recognize for coprolite, bone or bites at the moment. Maybe it would help to focus on one visual task at a time. Perhaps some really clear photos (with scale bar) of the characteristics that you think show it is a coprolite? Then bone? Then bites? The following paper might be useful in your deliberations: https://www.schweizerbart.de/papers/njgpa/detail/296/93795/A_Paleocene_vertebrate_bitten_crocodilian_coprolit?af=crossref When we published it, one of the reviewers gave us a similar test: Why do you think it is a coprolite in the first place? 2 Link to comment Share on other sites More sharing options...
jdp Posted January 30, 2021 Share Posted January 30, 2021 I'm seeing crystalline pyrite and calcite. I'm not seeing any bone. Maybe a better photo might clarify this? 1 Link to comment Share on other sites More sharing options...

Randyw Posted January 30, 2021 Share Posted January 30, 2021 @jdp is correct. I found some of these in some Richards spur Permian matrix I searched through. I was curious so I disassembled a couple and that’s all they were. 1 hour ago, jdp said: I'm seeing crystalline pyrite and calcite. Link to comment Share on other sites More sharing options...
