"Ischyrosaurus" (meaning "strong lizard", for its large humerus; name in quotation marks because it is preoccupied) was a genus of sauropod dinosaur from the Kimmeridgian-age Upper Jurassic Kimmeridge Clay of Dorset, England.
History and taxonomy
"Ischyrosaurus" is based on a partial humerus (NHMUK R41626) found in 1868.[1] John Hulke described it briefly in 1869,[1] then named it in 1874.[2] 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 was initially synonymized with Ornithopsis to create the new combination O. manseli,[3] then with Pelorosaurus as P. manseli.[4][5][6] Upchurch et al., in their review of sauropods (2004), listed it as a dubious sauropod.[7] 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.[8]
Paleobiology
As a sauropod, it would have been a large quadrupedal herbivore.[7]
