Arctic dinosaurs are only 20 years old

Scientists say the Arctic dinosaur is about 6 meters long and weighs 4 tons, short life span and more difficult to live than other dinosaurs.

Research reports based on fossils of millions of years of dinosaurs eating Arctic plants showed that the dinosaurs only live and survive for a short period of about 20 years, due to illness or distress.

According to the researchers, based on the fossil femur analysis of the Arctic dinosaur named Pachyrhinosaurus, they identified the Pachyrhinosaurus dinosaurs that grew fast and mated in adulthood (9 years old) and died in age around 19 or 20 years old.

Through the study of fossil samples, scientists determined that the Pachyrhinosaurus dinosaurs are horned dinosaurs belonging to the dinosaur group Ceratopsidae . Arctic dinosaurs are big dinosaurs, live in colonies and eat plants.

It is also possible that extreme temperatures in Alaska are the reason why Pachyrhinosaurus dinosaurs do not live long and hard to live. This explains why this dinosaur has a shorter life cycle than other dinosaurs of the same time.

Scientists hope, this study will be the clearest evidence of the activity of migratory animals. Currently the largest collection of Arctic dinosaurs in the world is being stored at the University of Alaska Museum, Fairbank City, Alaska State (USA).
