Praefectus Posted July 25, 2020 Share Posted July 25, 2020 Hi. I was wondering if anyone could help me identify these trilobites. Thanks for your help. The first two are Moroccan trilobites. I think they belong to the genus Calymene, but I am not sure. I have an ID card that says they are from the Ktaoua Group, Anti-Atlas Region, Morocco, Upper Ordovician. Can anyone confirm this? Thanks. This is another trilobite from Morocco. I think it is Proteus sp., but would like confirmation. My ID card says its from Ofaten, Morocco and is Middle Devonian in age. Is it correct? Last, I have some trilobites that I think are from the Wheeler Shale. I think they are Elrathia. Unfortunately, I don't have more information on them. I received them as a gift from my dad when I was around 5. I didn't think to take down notes on location, formation, and age at the time. 1 1 Link to comment Share on other sites More sharing options...
Huntonia Posted July 25, 2020 Share Posted July 25, 2020 I believe the first two are flexicalymene ouzreghi. The next is definitely a gerastos, probably tuberculatus. The first wheeler shale bug is an elrathia. A closer pic of the second would help, but I think it's also elrathia. 1 Link to comment Share on other sites More sharing options...

Huntonia Posted July 25, 2020 Share Posted July 25, 2020 Okay, this one's a little trickier, for the most part it looks like a normal elrathia, except for the genal spines. The spines on this one seem longer and thinner than is typical from the elrathia I've seen. Maybe it's a less common species or some developmental phase 1 Link to comment Share on other sites More sharing options...
