Hi all!
Very excited to find this crinoid on the very edge of a cliff and cleaned it just a little to reveal this tiny 4mm wide trilobite pygium right next to it. Using Missourian's key, I think the crinoid is Aglaocrinus ?
The trilobite doesn't look exactly like the pygidiums I have of Ameura so not sure on that one - thoughts?
Am I close? Should I try to clean more of the crinoid? The piece is only another inch or two thick.
Thanks for any help!! Bone
