Shark skeletons are composed of cartilage and not bone, and cartilage fossilizes but rarely. In 1964, shark expert, L. S. Glikman recognized the transition of Otodus obliquus to C. auriculatus and moved C. angustidens to genus Otodus. 65–156, pl.

Scientists suggest that this shark at least reached 9.1 metres (30 ft) in total length (TL), with a maximum length of 12.2 metres (40 ft). The Swiss naturalist Louis Agassiz, first identified this shark as a species of genus Carcharodon in 1835. O. angustidens was an apex predator and likely preyed upon penguins, fish, dolphins, and baleen whales. Some teeth have been excavated from the sediments of the Potomac River in Maryland, USA, Ypres clay in Belgium, and western Kazakhstan, which are morphologically very similar to Otodus teeth but with lightly serrated cusplets and a serrated cutting edge. & ESPINOSA-ARRUBARRENA, L.

As is the case with most extinct sharks, this species is mostly known from fossil teeth and some fossilized vertebral centra. & GAENGLER, P. & FABRITIUS, H.-O.

The complete Otodus obliquus to C. megalodon transition then became clear and has since gained the acceptance of many other experts with the passage of time. This unique specimen is around 26 million years old. C. angustidens was a widely distributed species with fossils found in North America, South America, Europe, Africa, New Zealand, Japan, and Australia. This shark is related to fellow extinct megatoothed sharks, such as Carcharocles auriculatus and Carcharocles megalodon. Geognotische Beschreibung Bayern, 1: 950 p., 26 fig., 42 pl.
