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.
