Megaselachus is an extinct genus of otodontid shark. In the past, this particular genus has been used to house other otodontids, such as the famous megalodon. It is sometimes considered a subgenus of Otodus, or merged with other related genera such as Carcharocles.[1] The genus lived during the Miocene. Only a single species can be confidentially placed in the genus, M. subauriculatus.
