Dacentrurus was a large heavily built stegosaurid adorned with plates and spikes. Eggs thought to be those of Dacentrurus were discovered in Portugal. It is one of the earliest stegosaurid discoveries. On May 23, 1874, James Shopland reported to Professor Richard Owen that he had found a fossil skeleton at the Swindon Great Quarry in Wiltshire. It was originally named Omosaurus but, it turned out that name had already been used. It was then named Dacentrurus. Dacentrurus is believed to have shoulder spikes similar to the Kentrosaurus of Africa and Huayangosaurus of China. It is closely related to an long necked Stegosaurus named Mirigaia.
