Otodus poseidoni is an rare extinct dubium species of shark of the genus Otodus and the family Otodontidae. It lived during the Middle Eocene period, between 41.2 and 36 million years ago, in the Bartonian and Priabonian.[1]
Taxonomy
[edit]Otodus poseidoni was discovered in 1999, and was initially classified in the genus Carcharocles. In 1999, it was moved to the genus Otodus, and Carcharocles poseidoni was a dubious and invalid binominal name.[citation needed]
Size
[edit]Otodus poseidoni was a large species of shark. It measured 11–12 m (36–39 ft) long.[2] Otodus poseidoni hunted whales, seals, penguins and squid.[3]
