Eustreptospondylus was a medium-large sized Late Jurassic nomadic islander predator. When it was first discovered it was assigned to the 'wastebasket' genus of Megalosaurus, but it has in the last few decades been reassigned as its own species, Eustreptospondylus.
It is a fairly well known English Dinosaur, part of the Oxford Clay Deposits and one of the most enigmatic Theropods of this region of Europe during the Mid-Late Jurassic Period. It is known from 167-149) and is shown in Walking With Dinosaurs to have endured to 149 Million Years Ago, which is probable anyway.It was depicted as an opportunistic predator, scavenging and fighting over carrion with members of its own kind. Even so, it is said to have been the largest of the 'Islanders Dinosaurs' and definitely would be a deadly carnivore in its own right at 5-7 metres long. A partial skeleton of the Eustreptspondylus is on display at the Oxford University Museum of Natural History in Great Britain, along with a Walking With Dinosaurs type Model of its head and neck made by the same animatronics organisation that made the Walking With Dinosaurs props (Crawly Creatures)
Eustreptospondylus featured in Cruel Sea, the third Walking with Dinosaurs episode. In the beginning scene, one of them was snapped up by a Liopleurodon. Later on, one of them is seen trying to catch a Rhamphorynchus, to eat. The Rhamphorynchus escape. At the end, though, two of them feast on the beached Liopleurodon, and it is likely many more Eustreptospondylus will arrive soon, to take advantage of all this food.
