Otodontidae is an extinct family of sharks belonging to the order Lamniformes. Its members have been described as megatoothed sharks.[1][2] They lived from the Early Cretaceous to the Pliocene, and included genera such as Otodus, including the giant megalodon.[3] Recent studies of the newly described genus Megalolamna indicate that the members of the genus Carcharocles should be reclassified as members of the genus Otodus.[4] The genus Cretalamna which lived from the mid-Cretaceous-Paleogene is believed to be directly ancestral to Otodus, and thus to megalodon.[5]
