Otodus obliquus, previously known as Lamna obliqua was one of the earliest mackerel sharks. Their teeth are noted for their wide triangular crown and large side cusps (occasionally multiple side cusps). Large Otodus obliquus teeth are not easily located in the phosphate pits in Atlas Mountains of Morocco, but can...
