Titanites is an extinct ammonite cephalopod genus within the family Dorsoplanitidae, that lived during the late Tithonian of the Late Jurassic. Its fossils have been found in Canada and the United Kingdom.
Description
Species of the genus Titanites can reach large sizes, with a diameter over 60 centimetres (2.0 ft) for Titanites giganteus and 90 centimetres (3.0 ft) for T. anguiformis. Much larger species, Titanites occidentalis with estimated diameter about 137 centimetres (4.49 ft) is reassigned to genus Corbinites. They were fast-moving nektonic carnivores.
