Eustreptospondylus - Meaning:well curved vertebra 

Eustreptospondylus (ewe-strep-toe-SPON-die-luss), in reference to the arrangement of the spine in the original fossil) was a genus of megalosaurid dinosaurs from the Callovian stage of the Middle Jurassic period (164.7-161.2 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).

Eustreptospondylus is thought to have been between 5-7 metres long (17-23 feet) and around 2 metres tall (6 feet 6 in).

It was carnivorous, bipedal and had a stiffened tail. It was a typical theropod, with powerful hind limbs, erect posture and small forelimbs.
