Abstract

Amylodon karamysh sp. nov. (Chondrichthyes, Holocephali, Chimaeridae) is described from the Early Campanian (Late Cretaceous) of the Saratov Region, Russia. It is based on a single mandibular plate with a relatively short outer margin and four small median tritors. The morphology of the mandibular plate of A. karamysh appears to have evolved from the condition in the chimaerid Ischyodus, which implies that the shearing-type dentitions of Amylodon and Rhinochimaera were probably of independent origin.
