Taxonomy
Cetiosaurus humerocristatus was named by Lydekker (1888). Its type specimen is BMNH R44635, a limb element (left humerus), and it is a 3D body fossil. Its type locality is Smallmouth Sands (BMNH), which is in a Kimmeridgian marine claystone in the Kimmeridge Clay Formation of the United Kingdom.

(1991) and Delair (1993); it was misspelled as Ceteosaurus humerocristatus by Lydekker (1904); it was considered a nomen dubium by Blows (1995); it was recombined as Duriatitan humerocristatus by Barrett et al. (2010).
