Introduction. Ptychodus is a highly specialized extinct genus of the family Ptychodontidae (Elasmobranchii). It is characterized by distinctive grinding-type (durophagous) dentition and is known from the Albian–Campanian (–70 Ma) stages of the Cretaceous Period (Cappetta, ).It has a global distribution and is well represented in the fossil record by isolated teeth.

Paige Winter, 17, lost a leg to a shark attack in June She was attacked off the North Carolina coast, and according to a family Facebook post, Winter's father, Charlie, "punched the shark in. According to these new data, it appears reasonable to remove Heteroptychodus from the family Ptychodontidae.

Based on similar ornamentation pattern, Heteroptychodus and Isanodus are closely related (Cuny et al.,Cuny, ) but their relationships with Ptychodus Agassiz, and Hubeiodus are currently difficult to assess.

Ptychodus is a Cretaceous shark genus occurring in Albian to Early Campanian marine deposits of North and South America, Europe, Africa and Asia (Cappetta ). The genus is known primarily by its teeth, which are characterized by a massive crown suited for crushing shelled macroinvertebrates (durophagy: e.g., see Kauffman ; Stewart a).

Patterson () suggests that Hylaeobatis arose from a homodont species of the hybodontid genus Lonchidion, and that Hylaeobatis, a member of the family Ptychodontidae, gave rise to the genus Ptychodus.
