connorp Posted May 23, 2020 Share Posted May 23, 2020 I feel like this is a smattering of disarticulated fish bones, but I'm not positive. The preservation is not amazing so even under magnification I'm not sure if these are bone or not. Found in Pennsylvanian black shale in Illinois. Any thoughts? @RCFossils Various levels of magnification Link to comment Share on other sites More sharing options...

RCFossils Posted May 24, 2020 Share Posted May 24, 2020 I am leaning more towards these being plant fragments but it is difficult to say for sure. 2 Link to comment Share on other sites More sharing options...
jdp Posted May 24, 2020 Share Posted May 24, 2020 Could be. What does fish material typically look like in these rocks? Link to comment Share on other sites More sharing options...
Strepsodus Posted May 24, 2020 Share Posted May 24, 2020 My initial thought was fish gill arches. I’m not sure though. Link to comment Share on other sites More sharing options...
