Callovosaurus

Callovian lizard

• Callov(ian) · Latin (geologic stage name) · from Callovium, Latinised Kellaways, the stage of the Middle Jurassic
• sauros · Greek · lizard

The name combines "Callovian", the geologic stage of the Middle Jurassic in which the fossil was found, with the Greek word for lizard. The Callovian itself is named after Kellaways in England (Latinised as Callovium). The single species is Callovosaurus leedsi, honouring Alfred Leeds, who collected the Oxford Clay fossil.

A small ornithopod, usually considered a dryosaurid, known only from a partial femur and few other scraps. The species was first described by Lydekker in 1889 as Camptosaurus leedsi and moved to its own genus by Galton in 1980. Because the material is scanty, it is often regarded as a nomen dubium, though some authors treat it as a possibly valid dryosaurid.
