Gramps Posted June 24, 2020 Share Posted June 24, 2020 Folks, I found this fossil mollusk from a shale deposit in Northeastern Oklahoma. The shale is of Pennsylvanian age (probably Chanute formation), and contains other marine fossils. I would appreciate any help with ID. Best wishes. 1 Link to post Share on other sites
DPS Ammonite Posted June 24, 2020 Share Posted June 24, 2020 Looks like Trepospira, a common Pennsylvanian species in north Texas. 2 Link to post Share on other sites
Gramps Posted June 24, 2020 Author Share Posted June 24, 2020 Yes. That does look like the right one. Thanks so much for your help! Link to post Share on other sites
