Genuine fossil sharks teeth from the Late Cretaceous to the early Eocene periods of North Africa, up to 70,000,000 years.

The Otodus obliquus was a very large Macro-predatory shark with the largest recorded tooth measuring 10.4cm in length. With each discovery, we are able to determine more about these powerful sharks which roamed the prehistoric seas of the Cenozoic era. Otodus was a fearsome predatory shark growing to a maximum length of 39 feet. Their prey being smaller marine mammals including smaller sharks. Scientist and palaeontologists theorise the Otodus obliquus ancestry connects to that of the great Megalodon from the Miocene era, evolving for around 30,000,000 to 40,000,000 years and now down we can enjoy the modern Great white sharks. This is the lineage of Carcharocles as we understand it today. 

As like most elasmobranchs, the skeletons of Otodus obliquus sharks were cartilaginous, cartilage easily is broken down by bacteria resulting in most discoveries missing the skeletal structures which can be seen in many other vertebrate fossil depositions.
