[4] The largest individuals were about 11–12 metres (36–39 ft) long. This shark is related to another extinct megatoothed shark, the famous Otodus ...
Sharks could be facing extinction over the next couple of decades. Human interference is largely to blame for the species interference. Overfishing of sharks has increased as the global demand has ...
The fossils of Otodus sharks indicate that they were very large macro-predatory sharks. [7] The largest known teeth of O. obliquus measure about 104 millimetres (4.1 in) in height. [8] The vertebral centrum of this species are over 12.7 cm (5 inch) wide. [7] Scientists suggest that O. obliquus would have measured about 8–9 metres (26–30 ft ...
