Slow Walker Posted February 4, 2023 Share Posted February 4, 2023 Found what looks like fish jaw with tooth and skeleton. There are many pieces of this fossil but only showing part with jaw. Was found poorly preserved in Pierre shale SD. Wondering which fish species it might be? Thanks! Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 4, 2023 Share Posted February 4, 2023 Need better, in focus, in light photos.

Mostly wondering about tooth. How about these? My camera seems to focus on one part of the image making other parts out of focus. When I try to get straight on photos the shadows form because of over head light. Link to comment Share on other sites More sharing options...

I have not encountered striations on Xiphactinus teeth. They are typically very smooth. This isn’t anything I recognize. 1 Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...
