Eustreptospondylus ( ; meaning "true Streptospondylus") is a genus of megalosaurid dinosaur, from the Callovian stage of the Middle Jurassic period (some time between 165 and 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). It might have foraged on shorelines for carcasses and marine life.
