Species synonymy

Ptychocorax is an extinct genus of mackerel sharks that lived during the Late Cretaceous. It contains three valid species that have been found in Europe and Asia.[1][4] It was originally identified as a hybodontiform,[2] but was later reidentified as an anacoracid.[1][4] It has also been considered to belong to its own family, Ptychocoracidae.[5] Ptychocorax is characterized by its unique dentition, combining Squalicorax-like, cutting anterior teeth with Ptychodus-like, crushing posterior teeth.[1][4]
