Duriatitan is agenus oftitanosauriformsauropoddinosaur that lived in theLate Jurassic in what is now England. Theholotype specimen ofDuriatitan, BMNH 44635, is a partial leftupper arm bone which was found by R.I. Smith nearSandsfoot,Weymouth in the lowerKimmeridge Clay fromDorset. Thetype species,D. humerocristatus, was described in 1874 byJohn Hulke as a species ofCetiosaurus and was noted as being similar to that ofGigantosaurus. Thespecific name refers to the deltopectoral crest,crista, on the upper arm bone,humerus.[1] The specimen was assigned to its own genus byPaul M. Barrett,Roger B.J. Benson andPaul Upchurch in2010. The generic name is derived from theLatin name for Dorset,Duria, and GreekTitan.[2]Thomas Holtz estimated its length at 25 meters (82 ft).[3]
Gigantosaurus megalonyx was once synonymised withDuriatitan whileD. humerocristatus was still a species ofOrnithopsis.[4]
