Fun facts
Dacentrurus was one of the largest stegosaurs, about as long as a school bus.1
Dacentrurus had two rows of small plates on its neck and two rows of long spikes on its tail.1
Its name was changed from Omosaurus because that name was already used for a different ancient reptile.1
The gut of Dacentrurus was especially broad, suggesting it had a large belly for digesting plants.1
