considered diagnostic, the more complete specimen BMNH R3078 was referred to the new taxon Cetiosauriscus stewarti, which was then designated as the type species of Cetiosauriscus as it contained the material Huene had originally named the new genus for. Cetiosaurus leedsi was then assigned to an intermediate member of Brachiosauridae, considered to be a proper species of Ornithopsis, or an improper species of Ornithopsis that is an indeterminate eusauropod. Ornithopsis greppini was given the new genus name Amanzia in a 2020 redescription of the original material. As Ischyrosaurus was used earlier by Edward Drinker Cope for the non-mammalian genus Ischyrotherium in 1869, the name "Ischyrosaurus" cannot be used for I. manseli, and so the species was retained as Ornithopsis manseli by David Martill and colleagues in 2006. The species has also been considered as Pelorosaurus manseli. Upchurch et al., in their review of sauropods (2004), listed it as a dubious sauropod. A 2010 overview of Late Jurassic sauropods from Dorset noted that O. manseli shared features seen in both Rebbachisauridae and Titanosauriformes, but lacked features to nail down its exact phylogenetic position. Description The Ornithopsis hulkei holotype is basically a centrum lacking the neural spine. The vertebra is heavily pneumatised, filled with large cavities, camellae. It is narrow, tall, has a ridge on the underside, is opisthocoelous and has a posteriorly placed deep subtriangular pleurocoel over two thirds of its length. These features are compatible with a placement within the Titanosauriformes.
