Crinoid thecae of Haplocrinites from the Devonian of the Holy Cross Mountains

Crinoid thecae of Haplocrinites from the Devonian of the Holy Cross Mountains

A collection of crinoid thecae of Haplocrinites from the Devonian of the Holy Cross Mountains is described. Morphometric analyses revealed that these thecae likely represent the same species displaying a wide range of morphologic variation. It has been argued that H. aremoricensis is a junior synonym of H. boitardi. The study indicates that traditional classifications of haplocrinitids require substantial revision.
