Abstract

The vomerine toothplate of a chimaerid holocephalan (Chondrichthyes) is described from the Emael Chalk (Maastricht Formation, Maastrichtian, Upper Cretaceous) of Eben-Emael, Belgium. A survey and discussion of the vomerine toothplates of Mesozoic chimaeroids confirms the suggestion that the presence of transverse ridges on the post-oral surface of the toothplate is characteristic of chimaerids.
