Information

Achillobator was a giant raptor dinosaur that lived in Asia. It was discovered in 1999 and scientists are still studying this huge meat-eater. This dinosaur was similar in size to the North American Utahraptor and was probably one of the most vicious hunters of its time. It has made scientists rethink their ideas about the raptor family in Asia.

Further study is needed to firmly assign Achillobator to the dromaeosaur family. Its initial assignment to this group is based on a number of shared characteristics, but these findings are preliminary.
