Can anyone help me find information on a particular crinoid fossil discovered in Oklahoma in the 70's or 80's. I don't have much information on it, but it is supposed to be the largest crinoid fossil ever recovered. I heard that the fossil might be on record at the Smithsonian, but searching web pages and taking the "virtual tour" were not productive for my search. Can anyone help ?
