Evolution of Delocrinus to Paradelocrinus, and Description of Stuartwellercrinus argentinei sp. nov.

Published online by Cambridge University Press:  01 May 2009

Abstract

The transition of Delocrinus to Paradelocrinus is demonstrated by a group of specimens collected by Mr. Allen Graffham from the lola limestone of Kansas. Description of Paradelocrinus iolaensis sp. nov. is given, and the geological range of the Permian genus Stuartwellercrinus is taken into the Pennsylvanian (Upper Carboniferous) with the presentation of Stuartwellercrinus argentinei sp. nov. from the Wyandotte limestone of Kansas.
