Eustreptospondylus

Eustreptospondylus ("well-curved vertebra", in reference to the arrangement of the spine in the original fossil) is a genus of megalosaurid dinosaur, from the Callovianstage of the Middle Jurassic period (165 to 161 million years ago) in southern England, at a time when Europe was a series of scattered islands (due to tectonic movement at the time which raised the sea-bed and flooded the lowland). The only known specimen of Eustreptospondylus may not be fully grown, and was about 4.63 metres (15.2 ft) long.^[1] It was carnivorous, bipedal and had a stiffened tail. It was a typical theropod, with powerful hind limbs, erect posture and small forelimbs.
