Abstract

A collection of fossils from the Doniphan Shale, Virgilian Stage, Upper Pennsylvanian contains a small ophiuroid identified as Archaeophiomusium burrisi (Miller). The discovery of the Iowa specimen lowers the lower boundary of the range-zone of this species and considerably extends its geographic distribution. The ophiuroid is associated with at least seventeen other species of marine invertebrates. Like specimens collected from the Permian of Kansas and Oklahoma, the Iowa specimen is in rock classed as shelly fades sensu LaPorte (1962).
