Achillobator is a genus of dromaeosaurid dinosaur that lived during the Late Cretaceous period around 90 million years ago, in what is now Mongolia. Its name means “Achilles hero,” referencing its presumed predatory prowess and the Greek mythological hero Achilles.

Achillobator was a medium-sized dinosaur, measuring approximately 16-20 feet long and weighing around 500-1,000 pounds. It had a long, slender body with long arms equipped with sharp, curved claws, suggesting it was a formidable predator. This dinosaur had a long tail that may have provided balance while running and maneuvering. Achillobator had a slender snout filled with sharp, serrated teeth, which it likely used to tear into the flesh of its prey. It is believed to have been an active and agile hunter, preying on small and medium-sized dinosaurs, as well as other animals in its ecosystem.

Although relatively little is known about Achillobator due to limited fossil remains, its discovery has provided valuable insights into the diversity and evolutionary adaptations of dromaeosaurids during the Late Cretaceous period.
