恐竜説明：

Dacentrurus was the first from the stegosaur family to be described from the fossil record. In 1875 Sir Richard Owen first said that these  bones belonged to Omosaurus, but that name had already been used for another animal. In 1902 the palaeontologist Frederic Lucas intro‑ duced the name we use today. Dacentrurus seems to have lived throughout Western Europe, though most remains have been found in southern England.

Scientists have argued fiercely about the size of this animal. Some have suggested that individuals may have reached 10 m (33 ft) in length and weighed in at as much as 6 tonnes. Dacentrurus had long front limbs and spines, rather than plates, along the length of its back. It is thought, therefore, to have been a primitive stegosaur. No skull remains have been found from the various parts of Europe where Dacentrurus is known to have lived. It is assumed that the skull was quite small and housed a tiny brain. The size of the legs suggests that it was a heavily built stegosaur that 'grazed' on quite soft plant material.
