connorp Posted November 2, 2023 Share Posted November 2, 2023 I'm looking for some help IDing this cephalopod fossil I collected from the Silurian (Racine Dolomite) of northern Illinois. The specimen is just a slice of the entire cephalopod unfortunately, so maybe it will be tough to ID. Any help either way is appreciated. @aek Come across anything like this before? 2 Link to comment Share on other sites More sharing options...
piranha Posted November 2, 2023 Share Posted November 2, 2023 Uranoceras hercules looks like a possible match from this classic monograph: Foerste, A.F. 1925 Notes on Cephalopod Genera; Chiefly Coiled Silurian Forms. Journal of the Scientific Laboratories of Denison University, 21:1-69 Foerste - 1925.pdf 3 Link to comment Share on other sites More sharing options...
