Description

Late Devonian

Foreknob Formation

Bedford County, PA, USA

Large 88mm disc on 200mm slab. First we have seen. Closely resembles other described paropsonomids like Discophyllum and Eldonia

Problematica.

This is a mystery that appears to be related to other mysteries – animals that have been proposed as cnidarians and relatives of early echinoderms.

This one is for collectors who like to keep it weird.
