I need some more help getting the right name for some pieces of goniatites from Jacksboro. I think these are the same because of one similar feature in particular. I would like to be sure since these will be with the rest of my Jacksboro collection in a temporary display at the Heard Museum in McKinney Texas dedicated to amateur collecting. These range from 20 to 50mm in size. The whorl is somewhat compressed with a rounded venter and faint tubercles on the umbilical margin especially on the smaller ones. The sutures are not complete enough for a good ID based on that. You can see transverse, flexuous lirae here and here and longitudinal lirae somewhat like "Agathiceras" seen last as I rotate it through in these three views here producing a cross-hatch pattern visible here

I found these today in Jack county, TX not far from the Wise county border. I’m not sure what the formation is there, but I think it could be either Jasper Creek or Alluvium. I don’t know much about the Alluvium, which is Cenozoic, Quaternary. I’m not sure I’ve ever hunted in the Cenozoic so I’m not sure what would characterize it. I’m learning though. I’d say the material resembled Pensylvania. Pic 1 & 2 are side the 2 sides I’m guessing that pic 1 is the dorsal valve side (there’s a convex vertical part running down the middle of the shell). # 2 is the pedical valve side and there’s a concave vertical part running down the middle of the shell. But I could be wrong on which is which.
