Curt P Posted June 29, 2023 Share Posted June 29, 2023 Hi, I know this is pretty rough. I had been attributing it to Eldredgeops, but I find no mention of Eldredgeops in the Michigan or Ohio Dundee. However all the old writers mention Proetus crassimarginatus, which I think now is Crassiproetus. I don't know if there is enough here to distinguish, but the margin along the pygidium has bothered me all along for Eldredgeops. FYI there are only 5 trilobites mentioned in any of the literature for the Dundee down here. Pseudodechenella nodosa and planimarginata, Trypaulites, Coronura and Crassiproetus. Of course there are many Eldredgeops not many feet up, but none preserved anything like this. Thanks for any help you can give. 355471148_9576358892434785_6581400298562770854_n.mp4 1 Link to comment Share on other sites More sharing options...
Kane Posted June 29, 2023 Share Posted June 29, 2023 Not a Crassiproetus. Their pygidia are more convex and egg-like with a broad pygidial axis. Here's what they should look like: ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
