Titanites Explained

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

Species of the genus Titanites can reach large sizes, with a diameter over 60cm (20inches) for Titanites giganteus and 90cm (40inches) for T. anguiformis.^[2] Much larger species, Titanites occidentalis with estimated diameter about 137cm (54inches) is reassigned to genus Corbinites.^[3] They were fast-moving nektonic carnivores.
