English: Dacentrurus is a genus of stegosaurian dinosaur from the Late Jurassic to Early Cretaceous, discovered in what is now England. Dacentrurus was one of the largest stegosaurs, with some specimens estimated to reach up to 9 m in length, and weighing around 5 t. Though finds of this animal have been limited and much of its appearance is uncertain, it was a heavily built quadrupedal herbivore with plates and spikes along its back.
