Eucamerotus

Eucamerotus (meaning "well-chambered", in reference to the hollows of the vertebrae) was a genus of sauropod dinosaur from the Barremian-age Lower Cretaceous Wessex Formation (Wealden) of the Isle of Wight, England. History and taxonomy John Hulke erected the genus in 1872 for " R.2522", a neural arch found by William Fox near Brighstone Bay, but provided no species name. He considered the Ornithopsis hulkei lectotype referable to the genus. He later referred NMHUK R.2522 to Ornithopsis, synonymizing Eucamerotus with Seeley's name based on the discovery of additional vertebrae from the Isle of Wight. Later authors treated Eucamerotus as a synonym of Pelorosaurus. William T. Blows resurrected the genus in 1995 as a valid brachiosaurid, added the specific name and added the species epithet foxi, designating the various vertebrae that Hulke (1879, 1880) had referred to Ornithopsis as paratypes, while referring additional vertebrae and partial skeleton MIWG-BP001 to it. This last point has not been generally accepted; unfortunately, this skeleton has never been officially described.
