Hey group. I hope you're not getting tired of answering all my questions. Because...... I am requesting your expertise in a few more crinoid identifications. The information (as listed) I have on this specimen is it a Devonian Crinoid Flower from an estate sale collection from the early 1960's. It's listed(?) find location is Iowa, USA. It was originally purchased from Ralph E, Mueller and Son Phoenix, AZ in the early 1960's and was displayed in their store for several years until being sold. Help please!
