What is "otodontidae"

Otodontidae is an extinct family of sharks, belonging to the order Lamniformes. They lived from the Late Cretaceous to the Pleistocene, and included genera such as Carcharocles and Otodus. There is the possibility that if the Carcharocles sharks derived from Otodus, then Cretolamna would belong in this group. Some species of odontids reached huge sizes, including the possible member megalodon.
