Its type species, Omosaurus armatus, was named in 1875, based on a skeleton found in a clay pit in the Kimmeridge Clay in Swindon, England. In 1902 the genus was renamed Dacentrurus because the name Omosaurus had already been used for a phytosaur. After 1875, half a dozen other species would be named but perhaps only Dacentrurus armatus is valid.
Finds of this animal have been limited and much of its appearance is uncertain. It was the largest stegosaur measuring around 8–9 metres (26–30 ft) long and weighing up to 5–7.4 metric tons (5.5–8.2 short tons).
The relationships between Dacentrurus and other Dacentrurinae, such as Miragaia, are contentious.
