Fossil hunters say they have discovered a rare skeleton of a young Tarbosaurus dinosaur in the Gobi Desert that could yield important clues on the species.

The fossil, which is 70 million years old, is the first discovery of such a complete skeleton of a young Tarbosaurus, a carnivorous dinosaur related to the Tyrannosaurus, a Japanese company involved in the project said.

About 80 percent of the two-meter five-year-old’s skeleton has been discovered, according to a statement from biotechnology firm Hayashibara, which has been conducting research in the desert since 1993.

Researchers hope analysis of the well-preserved specimen will shed light on the difference between young and adult dinosaurs and their growth process, according to the company, which made the discovery in collaboration with paleontologists at the Mongolian Academy of Sciences.
