Bullsnake Posted November 13, 2012 Share Posted November 13, 2012 This opening post might be elementary to seasoned collector, but I hope it can be helpful to novices, or maybe someone out of their specialty. Despite size, and texture, note the suggestive shape between a Pennsylvanian shark tooth (Deltodus?) and Myalina(?) clam. The two larger specimens at top are the clams: At first I thought this was a cross-section of a shell. I'm glad I checked it out further. This is the same tooth from the above photos: Shells eroding from strata (different location): Steve Link to comment Share on other sites More sharing options...
Bullsnake Posted November 13, 2012 Author Share Posted November 13, 2012 (edited) Now for texture. Pennsylvanian shark tooth: Credit to Missourian for explaining this Worn oolites (Note the complete oolites in the surrounding matrix): Bryozoan (Fistulipora?) Note the rougher texture, and appears to be same material as the matrix: I think you get the idea!
