(Prairie Grove, Arkansas, USA)
I was recently exploring a wild cave in Northwest Arkansas and I found this fossil stuck on the side of one of the canyon walls inside. It is a limestone cave and the canyon walls have a large number of crinoid stem segments embedded in them as well. I measured it with my calipers, I hope that is helpful. I have been comparing photos of fossils too it and I am at a loss for what it is...Hope you can tell me! Thanks
