A New Species of the Dual-mouthed Paracrinoid Bistomiacystis and a Redescription of the Edrioasteroid Edrioaster priscus from the Upper Ordovician Curdsville Member of the Lexington Limestone

Colin D. Sumrall, Bradley Deline
Published: 01 January 2009
Journal of Paleontology (2009) 83 (1): 135–139.
DOI: https://doi.org/10.1666/08-075R.1
... that this unusual arrangement is consistent with oral areas of other derived blastozoans bearing oral plates. Edrioaster priscus (Miller and Gurley) is a poorly known large edrioasterid edrioasteroid previously known only from specimens preserved in coarse beekite. The new material of this taxon allows...
