A skull ofCyamodus kuhnschnyderi Nosotti &Pinna 1993, from the Muschelkalk of wasselonne (Alsace, France)

Abstract

A partial skull from the upper Muschelkalk (mo3,praenodosus to lowernodosus Zone) of Wasselonne (Alsace, France) is described and identified as third specimen ofCyamodus kuhnschnyderi. The dentition of all species currently included in the genusCyamodus is discussed, and instances of individual variation are identified. In contrast to the type material, the new specimen ofCyamodus kuhnschnyderi has two pairs of premaxillary teeth, and thus adds incongruence to the stratophenetic trend of dental reduction previously identified within the genusCyamodus.
