Wondering if there is a thing called #FossilFriday. Maybe there should be. I randomly came across this closeup shot of giant crinoid stem pieces from 2009 at a Tucson Gem & Mineral show. The slab was about 4’ long with a few dozen fossils left protruding. If anyone likes I can share a link to an album. #Fossil #Crinoid #paleontology

@cobalt123 You sure they aren't fish vertebrae?

@AdamStuartSmith !!!

I just now learned they may be from fish!!! I looked at my fossil photos online and someone made this same comment in Flickr. I will link later to the other photo which may help ID. From a vendor whose inventory is from Morocco.
