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.

[4] In 2001, a discovery of the best preserved Carcharocles angustidens specimen to date by two scientists, Michael D. Gottfried and Ewan Fordyce, has been presented by the team as evidence for close morphological ties with the extant great white shark, and the team argued that Carcharocles angustidens, along with all other related megatooth sharks, including Carcharocles megalodon, should be assigned to Carcharodon as was done before by Louis Agassiz.,[5] although this is not internationally accepted by the scientific community.

[5] Smaller individuals were about 6–6.6 metres (20–22 ft) long, still larger than the avarage extant great white shark.

To date, the best preserved specimen of this species have been excavated from New Zealand, which comprises 165 associated teeth and about 35 associated vertebral centra.

O. angustidens teeth are noted for their triangular crowns and small side cusps that are fully serrated.
