Species: Otodus Obliquus
Otodus is an extinct, cosmopolitan genus of mackerel shark which lived from the Paleocene to the Pliocene epoch. The name Otodus comes from Ancient Greek ὠτ- and ὀδούς – thus, "ear-shaped tooth" referring to the shape of their teeth..
Size and habitat
Otodus species varied in size, with some, like O. obliquus, reaching lengths of 8-9 meters (26-30 ft) and others like O. angustidens growing to 11-12 meters (36-39 ft).
Otodus had a cosmopolitan distribution, inhabiting oceans worldwide, including coastal and open ocean environments.
Fossils of Otodus have been found on every continent, including Antarctica.
Evidence suggests that Otodus, like modern sharks, utilized coastal areas as nurseries for their young.
Diet and hunting
Otodus was an apex predator, preying on a variety of marine animals, including fish, sea turtles, cetaceans (whales), and sirenians (manatees and dugongs).
Studies suggest that Otodus, including its most famous descendant Megalodon (Otodus megalodon), were flexible in their dietary choices and could also feed at lower levels of the food chain, according to a May 2025 Phys.org article.
Possible evidence suggests that Otodus might have even hunted large raptorial sperm whales. A tooth of a small sperm whale found with bite marks on its roots indicates that an Otodus chubutensis or Megalodon might have attacked the whale's head, possibly breaking its jaw. This marks the first known instance of such an interaction recorded in the fossil record.
Otodus possessed strong sensory capabilities, including a good sense of smell and sight, as well as electroreceptors to detect prey.
Fossil remains
The cartilaginous skeletons of sharks do not preserve well. Therefore, Otodus is primarily known from fossilized teeth and isolated vertebral centra.
Otodus teeth are large and triangular, with smooth cutting edges and visible cusps. Some teeth show signs of evolving serrations.
Morocco's phosphate mines are a rich source of Otodus teeth, though they are also found in other locations globally.
Otodus is considered the ancestor of Megalodon (Otodus megalodon). Their evolutionary lineage is evidenced by the similarities and progressive development of serrations in their teeth.
