Ischyrosaurus
"Ischyrosaurus" was a genus of sauropod dinosaur from the Kimmeridgian-age Upper Jurassic Kimmeridge Clay of Dorset, England. It was once synonymized with the Early Cretaceous-age Pelorosaurus."Ischyrosaurus" is based on a partial humerus found in 1868. John Hulke described it briefly in 1869, then named it in 1874. The genus is preoccupied by a name Edward Drinker Cope coined in 1869.
Like most sauropod remains from the Upper Jurassic-Lower Cretaceous of Europe, it became part of the Pelorosaurus-Ornithopsis taxonomic tangle, being referred first to Ornithopsis as O. manseli, then to Pelorosaurus as P. manseli. Upchurch et al., in their review of sauropods, listed it as a dubious sauropod. A 2010 overview of Late Jurassic sauropods from Dorset noted that Ischyrosaurus shared features seen in both Rebbachisauridae and Titanosauriformes, but lacked features to nail down its exact phylogenetic position.Paleobiology
As a sauropod, it would have been a large quadrupedal herbivore.
