The Otodontidae (English megatoothed sharks ) are an extinct family of sharks from the order of the mackerel shark-like (Lamniformes) and were found in all oceans from the Turonium (Upper Cretaceous) to the Pliocene .

They were set up in 1964 by Leonid Sergejewitsch Glikman . Fossil mackerel shark species are classified in the family, which differ from the recent mackerel sharks (Lamnidae) by their enormous teeth , but otherwise are so similar to the mackerel sharks that the Otodontidae are not recognized by all scientists. The teeth can be straight or curved, symmetrical or asymmetrical.
