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 ?
