A Devonian spiriferid brachiopod from Ohio which served as a host substrate for a colony of hederellids. Spiriferida is an order of extinct articulate brachiopod fossils which are known for their long hinge-line, which is often the widest part of the shell. In some genera (e.g. Mucrospirifer) it is greatly elongated, giving them a wing-like ...
