Achillobator is a fairly famous raptor due to its large size. Like Austroraptor and Utahraptor, it was on the larger end of raptor size, comparable to the raptors of Jurassic Park. In fact, it was about 5 to 6 meters long and 2 meters tall. It was found in the Bayan Shireh Formation in Dornogovi Province, Mongolia. It lived about 90 million years ago, in the Turonian age of the Late Cretaceous. It is only known from very fragmentary remains, however cladistic analyses have proven it is not a chimera (a mixture of different dinosaur fossils). It lived alongside the tyrannosaurid Alectrosaurus which Achillobator probably had to compete with for food. It also lived alongside Segnosaurus, Talarurus, Bactrosaurus, a sauropod, and an azhdarchid pterosaur.
