Cretalamna Kenolamna Megalolamna Otodus Palaeocarcharodon Parotodus?

Otodontidae is an extinct family of sharks belonging to the order Lamniformes.

[4] The genus Cretalamna which lived from the mid-Cretaceous-Paleogene is believed to be directly ancestral to Otodus, and thus to megalodon.

These dubious species are considered to be synonymus or are pending reassesment of their validity.
