Deltadromeus (meaning delta runner) is a large basal ceratosaurian theropod dinosaur from Northern Africa. It had long, unusually slender hind limbs for its size, suggesting that it was a swift runner. Two fossil specimens of a single species (D. agilis, or agile delta runner) have been described, found in Morocco, North Africa, which date to the late Cretaceous Period, about 95 million years ago.
