Study: Dinosaurs Survived Extinction in Cold Temperatures

News » Science & Technology

A new study shows that dinosaurs survived one extinction event in freezing temperatures. According to new data, dinosaurs that lived on Earth 200 million years ago not only reached the polar latitudes, but also felt great in the ice at low temperatures.

Until recently, it was believed that the era of dinosaurs ended as a result of meteorite impact on the Yucatan Peninsula in Mexico, but a new study has shown that these creatures managed to survive in sub-zero temperatures even in polar latitudes.

prevented the penetration of sunlight, resulting in severe cooling.

The temperature could drop to negative values, which killed cold-blooded reptiles, and dinosaurs that had time to adapt to the cold survived.

As it turned out, at that time even tyrannosaurs had primitive plumage.

“There is a stereotype that dinosaurs always lived in covered tropical jungle vegetation, however this new study found that areas at high latitudes experienced frost and were even covered in ice during periods of the year, — says Stephen Brucett, professor of paleontology at the University of Edinburgh. — Dinosaurs that lived in high latitudes were lucky to have winter “clothes” while their other Triassic rivals died out.”
