Alectrosaurus was a Tyrannosaur that hunted in Asia for Millions of years (87–78 Ma). It preyed on Saurornithoides, Oviraptors,and ornithischains , and occasionally Gigantoraptor (if it could get a chance). It appeared in the Episode "The Great Survivors" and dominated over the Oviraptorids, but because they changed their diet, the oviraptors can thrive in the area because they don't compete directly with the tyrannosaurs for food.

it was about 5 metres long and weighed about 1 tonne.
