A revision of the chimaeroid fishes (Holocephali, Chimaeroidei) from the British Cretaceous

Abstract

The preliminary results of a revision of the British Cretaceous chimaeroid fishes (Holocephali, Chimaeroidei) based on a study of museum collections are presented. The taxonomic composition (2 families, 9 genera, 20 species) and stratigraphic distribution of Cretaceous chimaeroid fishes are summarized. Some taxa, including Callorhinchus, Elasmodus, and Lebediodon are recorded from British Cretaceous for the first time.
