Achillobator is a dromaeosaurid theropod dinosaur that lived roughly 98 to 83 million years ago during the Late Cretaceous in what is now Mongolia, in Asia. It was among the largest dromaeosaurs; the holotype and only known individual of Achillobator is estimated at 5 to 6 m (16.4 to 19.7 ft) long. Achillobator was a moderately-built, ground-dwelling, bipedal carnivore. It would have been an active predator, hunting with the enlarged, sickle-shaped claw on the second toe.

About Achillobator dinosaur
As far as paleontologists can tell, Achillobator (the name, “Achilles warrior,” refers both to this dinosaur’s large size and to the large Achilles tendons it must have had in its feet) was a raptor, and thus in the same family as Deinonychus and Velociraptor.
However, Achillobator does appear to have possessed some quirky anatomical features that differentiated it from its more famous cousins, which has led some experts to speculate that it may represent an entirely new type of dinosaur.
Achillobator dinosaur Classification
Achillobator is a dromaeosaurid, a family of dinosaurs currently thought to be very closely related to birds. While the relationship of dromaeosaurids to other theropods is relatively well understood, the phylogeny within the family itself is not.
The more recent phylogenetic analyses, conducted by Longrich and Currie (2009) and Senter et al. show that Achillobator is a member of the subfamily Dromaeosaurinae, most closely related to North American forms like Utahraptor and Dromaeosaurus. Deinonychus and Velociraptor are also dromaeosaurids, but appear to represent a different branch of the family.
Achillobator dinosaur Habitat
We have four Achillobator, two males and two females. They live in a scrubby habitat, part of the Mongolia of the Cretaceous exhibit.
Achillobator was a carnivore. It lived in the Cretaceous period and inhabited Asia.
Achillobator dinosaur Facts
- Achillobator is a name derived from the combination of Mongolian and Greek words and literally means ‘Achilles hero’.
- Belonged to the raptor family of dinosaurs and was a ferocious carnivore.
- Weighing anywhere between 500 to 1,000 pounds, this carnivore could grow up to a length of 20 feet.
- Achillobator dwelt in the Central Asian plains (currently Mongolia) during the Late Cretaceous period, which was around 98 to 83 million years ago.
- This raptor was bipedal (walked/ran on two feet) and had a moderate build. It was a ground dwelling active predator.
