Otodontidae is an extinct family of sharks belonging to the order Lamniformes.Its members have been described as megatoothed sharks. [1] [2] They lived from the Early Cretaceous to the Pliocene, and included genera such as Otodus, including the giant megalodon. [3]
The fact that the bite marks were found on the tooth's roots further suggest that the shark broke the whale's jaw during the bite, suggesting the bite was extremely powerful. The fossil is also notable as it stands as the first known instance of an antagonistic interaction between a sperm whale and an otodontid shark recorded in the fossil record.

2024 was an "exceptionally quiet year" for shark bites around the world, with far fewer than usual, according to a new report released Tuesday by the International Shark Attack File. Worldwide ...
In 1964, shark expert, L. S. Glikman recognized the transition of Otodus obliquus to C. auriculatus and moved C. angustidens to genus Otodus. (See "external links" below) However, in 1987, shark expert H. Cappetta recognized the C. auriculatus - C. megalodon lineage and placed all related megatooth sharks along with this species in the genus ...
Confirmed attacks in 2024 dwarfed numbers reported in the previous year's International Shark Attack File, which recognized 91 global incidents, including 69 unprovoked bites and 22 provoked bites ...
The International Shark Attack File was established in 1958. Staff working on the shark attack surveillance have launched 6,800 investigations covering a period from the early 1500s to the present.
The otodontid sharks have been considered to have been ectotherms, so on that basis megalodon would have been ectothermic. However, the largest contemporary ectothermic sharks, such as the whale shark, are filter feeders, while lamnids are regional endotherms, implying some metabolic correlations with a predatory lifestyle.
