"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. It was once synonymized with the Early Cretaceous-age Pelorosaurus.
History and Taxonomy
"Ischyrosaurus" is based on a partial humerus (BMNH 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 became part of the Pelorosaurus-Ornithopsis taxonomic tangle, being referred first to Ornithopsis as O. manseli,[3] then to Pelorosaurus as P. manseli.[4][5][6]
Upchurch et al., in the most recent review (2004), lists it as a dubious sauropod of unknown affinities.[7]
Paleobiology
As a sauropod, it would have been a large quadrupedal herbivore.[7]
