In their review of sauropod species referred to Cetiosaurus, Upchurch & Martin (2003) concluded that ‘C.’ humerocristatus ‘is regarded as a distinct taxon referable to the Brachiosauridae’ but went on to state that ‘[w] e prefer to wait for more complete material before proposing a new name for this taxon’ (p. 213).

Marsh, an animal more quadrupedal in gait or walking more habitually on all fours, like the great _Cetiosaurus_, or "whale saurian," discovered near Oxford, England.

This animal is quite certainly not really a species of Cetiosaurus (hence the quote marks used from hereon), as it is highly different in detail from the humerus of Cetiosaurus oxoniensis, the type species of the genus (well, actually, C. oxoniensis is not yet the type species of the genus, but that’s a long and complex issue that I can’t go into right now).

The Hastings Beds Group has yielded Pelorosaurus conybeari (which is actually the same thing as Cetiosaurus brevis, but we won’t go there right now) and P. becklesii (which clearly isn’t congeneric with P. conybeari).

Based only on a big humerus (1.3 m long, though perhaps 1.7 m long when complete: see adjacent image) discovered at Weymouth, Hulke named it Ceteosaurus humero-cristatus: note that he used a spelling of the generic name that later fell out of favour (the original, and thus favoured, spelling is Cetiosaurus), and used a hyphen in the specific name (an action that is illegal under today’s nomenclatural rules).

Hypsilophodon, Cetiosaurus, Baryonyx) have proved globally important in terms of what they’ve told us about dinosaur evolution and diversity.
