Titanites is an extinct ammonite cephalopod genus within the family Dorsoplanitidae, that lived during the late Tithonian of the Late Jurassic.[1] Its fossils have been found in Canada and the United Kingdom.

## Description

A pair of Titanites giganteus fossils at Wollaton Hall

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.[2] Much larger species, Titanites occidentalis with estimated diameter about 137 centimetres (4.49 ft) is reassigned to genus Corbinites.[3] They were fast-moving nektonic carnivores.
