thumb|Life restoration of O. obliquus thumb|350x350px|Block with five Otodus obliquus teeth from the Ypresian of Khouribga, Morocco. Max Rouger Collection. Otodus is an extinct, cosmopolitan genus of mackerel shark which lived from the Paleocene to the Pliocene epochs.
==Description== All species are known from their fossilized teeth, and four of them (O. obliquus, O. auriculatus, O. angustidens and O. megalodon) are also known from their fossilized vertebral centra. Like other elasmobranchs, the skeletons of Otodus spp. were composed of cartilage, resulting in relatively few preserved skeletal structures appearing within the fossil record. The teeth of this shark are large with triangular crown, smooth cutting edges, and visible cusps on the roots. thumb|250px|A Anatomical terms of location#Teeth|lingual (tongue-side) view of O. obliquus teeth from the [[Eocene near Khouribga, Morocco]]
