Pelorosaurus (/pəˌlɒroʊˈsɔːrəs/ pə-LORR-oh-SOR-əs; meaning "monstrous lizard") is a genus of titanosauriform sauropod dinosaur. Remains referred to Pelorosaurus date from the Early Cretaceous period, about 140-125 million years ago, and have been found in England and Portugal.[citation needed] Thomas Holtz estimated its length at 24 meters (79 feet).[1]
The name Pelorosaurus was one of the first to be given to any sauropod. Many species have been assigned to the genus historically, but most are currently considered to belong to other genera. Problematically, the first named species of Pelorosaurus, P. conybeari, is a junior synonym of Cetiosaurus brevis.
