These are alot different than we find in Missouri. They were found in a road cut along I40 in Kansas. The grid is 1/4 inch

Looks like they are from the Upper Pennsylvanian period.

Crinoids in Mo range from Silurian to Devonian era.

I haven't had the luck to find a crinoid head yet. Waiting for the Mississippi river to get low to look for some.

Crinoids (Uintacrinus) are found in the Niobrara Chalk (Late Cretaceous) of Kansas and a formation in Colorado as well, I think.

Those cool free-floating crinoids are found out west, but I've never found any. Eastern Kansas has lots of crinoid pieces, but I have never found a head in KS.

Jimi -
check out Cape Rock Park along the river in Cape Girardeau. There are some really cool ones there.
