Mississippian- Missouri

Recommended Posts

Found in a creek bed in Boone County, Missouri. I’ve found several fossils there, but am having a hard time identifying a couple of them. From what I’ve been able to find out, they’re from the Mississippian period. I’ve tried to make the pictures as clear as possible. If you need more, please don’t hesitate to ask! Thanks in advance!

These are steinkerns of crinoids in chert. The actual fossil is gone, leaving a mold. That top one is really cool. You can see the stem as well as the calyx above. Neat find!

It is a mold of a crinoid head (the zig zag pattern) and some crinoid columns in chert.

My goal is to leave no stone or fossil unturned.
