Comments
There are some scientific theories in support of this shark being the great grandfather of C. megalodon. This species was one of the major oceanic predators of the Eocene and the shark at it's time was the largest of the Eocene sharks known in the fossil record. O. obliquus went extinct during the mid-Eocene and the largest shark to continue the line of mega-sharks was C. auriculatus. Both O. obliquus and C. auriculatus had cusps on both sides of the tooth root. O. obliquus teeth can grow up to a couple of inches implying the shark would have been anywhere from one and a half to twice the size of the largest Great White sharks of our modern day oceans though this is merely speculation and is based on the tooth to shark ratio modeled in modern C. charcarias.
