Oplosaurus (meaning "armed or weapon lizard" or "armoured lizard"; see below for discussion) was a genus of sauropod dinosaur from the Lower Cretaceous (Barremian stage) Wessex Formation of the Isle of Wight, England. It is known from a single tooth usually referred to the contemporaneous "wastebasket taxon" Pelorosaurus, although there is no solid evidence for this.

==History and taxonomy== In 1852 geologist Thomas Wright reported the find of a large reptilian tooth from the Wealden Clay near Brixton Bay on Wight. Wright had presented the find to several experts, among them Richard Owen, David Forbes, George Robert Waterhouse and Samuel Pickworth Woodward but only Gideon Mantell came with a useful suggestion pointing to a similarity with the teeth of the dinosaur Hylaeosaurus. Not convinced by this, Wright concluded that the tooth, in view of its sharpness, belonged to a carnivorous reptile of unknown affinities.
