Eucamerotus

Eucamerotus (meaning "well-chambered", in reference to the hollows of the vertebrae) is an extinct genus of sauropod dinosaur from the Early Cretaceous (Barremian) Wessex Formation (Wealden) of the Isle of Wight, England. The type specimen, part of a vertebra (one of the bones of the spine), was discovered in the autumn of 1869 by John Hulke. After confirming its point of origin with the Rev. William Fox, Hulke presented his find to the Geological Society of London in 1870. Two years later, he assigned to it the name Eucamerotus, though did not provide a species name. Eucamerotus was subsequently treated as a junior synonym of two existing sauropods, Pelorosaurus and Ornithopsis. In 1995, William T. Blows gave a species name, creating the combination Eucamerotus foxi. While the validity of the genus has continued to be questioned, a 2011 publication found it to be a valid genus of titanosauriform. Comparisons with the fossils of other macronarians suggests it may have reached up to 15 m (49 ft) in length.
