'Ornithopsis hulkei' Seeley, 1870

Stratigraphy
Wessex Formation
Lifestyle

A long-necked sauropod dinosaur, Ornithopsis was a browser, eating tough vegetation with its chisel-like teeth. It probably was only a visitor when it died, as there was insufficient vegetation to support a sauropod population.

Locality
Brighstone Bay, which is quite vague, but is the best I can offer I'm afraid...

Description of Material

(Don't understand all the terminology? visit the Glossary)

The only definitely identified specimens are an imperfect posterior dorsal vertebra, a right pubis and ischium. The vertebra has no distinguishing features that are not present in other brachiosaurs. The pubis has a distinct rounded foot at its distal end, which is also seen in Brachiosaurus, and in the ischium the dorsoventral length of the pubic articulatory surface is longer than the distance from the anteroproximal corner of the pubic process to the posterior edge of the bone. However, it is likely that the pelvic elements are not associated

Material is rare, so please report it if you find some...

How do I know if I've found a bone?
