Dinosaurs sauropods takes about 15 million years to traverse the supercontinent Pangaea. New study says there is a role for climate change that helped drive a large dinosaur is. Sauropods are a family of dinosaurs that includes creatures that ever lived on Earth. However, the question arises, why sauropods so long reaches of Greenland, from South America, where they first appeared? Already since a long time, this question has puzzled scientists and paleontologists. However, the new study quoted by the Independent, Tuesday (16/2/2021) showed major changes in the Earth's climate which allows the occurrence of migration.

But, despite all the continents are locked together, the dinosaurs sauropods this takes about 15 million years to reach the place which is now called Greenland. In the new study, Dennis Kent of the Lamont-Doherty Earth Observatory at Columbia University, and Lars Clemmensen from the University of Copenhagen has to calculate the travel time of the dinosaurs and reveal the role of climate change in helping the migration sauropods such.

The phenomenon of climate 200 million years ago, the Two researchers say that even though a herd of dinosaurs running just one mile per day, at which time they will need less time than 20 years to travel between South America and Greenland. Nevertheless, in a recent paper of a study conducted Kent and Clemmensen, they indicate the presence of the phenomenon of climate attractive. The phenomenon of climate change is thought to have helped the dinosaurs sauropods in the end the journey to Greenland.

Scientists examine the previous estimate shows that sauropods arrived in Greenland between 224 and 205 million years ago. However, the researchers painstakingly match the pattern magnetic ancient rock layers in the fossil site in all of South America, Arizona, New Jersey, Europe and Greenland. The results of the match resulted in a more precise estimate. That is, this indicates that sauropods arrived in what is now called Greenland about 214 million years ago. At that time, all the continents were joined and formed the supercontinent Pangaea. Nevertheless, the travel time of the dinosaurs sauropods towards Greenland still takes quite a long time.

"In principle, the dinosaur can walk from almost one pole to the other pole. There are no oceans in between. There is not a huge mountain. But it takes about 15 million years," said Dr. Kent. Researchers believe that there is a decrease in carbon dioxide (CO2) in the atmosphere is incredible in around the time of the sauropods will migrate at 214 million years ago. And this, said the scientist could be the key to unlock the mystery of why migration sauropods requires a very long time. Up to about 215 million years ago, the Triassic period has experienced CO2 levels are very high, with a concentration of about 4,000 parts per million, about 10 times higher than carbon stocks dioxide at this time.
