Description
Otodus obliquus is an extinct mackerel shark which lived during the Paleocene epochs. The shark is known mainly from fossil teeth and occasionally, fossilized vertebral centra.
Like other elasmobranchs, the skeleton of Otodus was composed of cartilage and not bone, resulting in relatively few preserved skeletal structures. Teeth are common, and occasional vertebra well known, but to find an associated vertebral column is incredibly rare, bearing in mind the cartiliginous nature of the shark skeleton.
The fossils of Otodus indicate that it was a very large predatory shark, often reaching 9 metres (30 feet) in length. The shark was widespread, with remains discovered in Africa, Asia, Europe, and North America.
