Ampheristocystis, a Silurian (Lower Wenlock) eocrinoid (Echinodermata, Blastozoa) from Indiana
TL;DR: The enigmatic blastozoan echinoderm Ampheristocystis concentricus, based on four specimens from the upper part of the Osgood Member, Salamonie Dolomite, southeastern Indiana, is most likely an eocrinoid, but it is presently unclear whether the life habits of this genus were more like that of the common Osgood diploporites or stemmed contemporaries such as Caryocrinites and Eucalyptocrinites.
