New fossil discovery shows dinosaurs have traveled across oceans



The new species of dinosaur, Ajnabia odysseus, a member of the plant-eating platypus family, was discovered in the rock in a Moroccan beak, dating back about 66 million years until the end of the Cretaceous period.

Although some platypus can be as long as 15 meters, experts say that Ajnabia is relatively small, only the size of a foal at 3 meters.

Experts were puzzled about how the dinosaur came to Africa, an island continent and was completely isolated by the deep sea during the Late Cretaceous period.

Platypus evolved in North America, and then spread to South America, Asia, and Europe.

Nicholas Longrich, a senior lecturer at the Milner Evolution Center at the University of Bath who led the study, describes the fossil discovery as “about the last thing in the world you expect.”

“It’s completely out of place, like finding a kangaroo in Scotland. Africa is completely isolated by water – so how did they get there?” Longrich said in a statement.

After studying Ajnabia’s teeth and jawbone, experts determined that it belonged to the subfamily Lambeosaurinae.

Experts say the lambeosaurs evolved in North America, before spreading across a terrestrial bridge to Asia, and colonizing Europe and then Africa, which is surrounded by giants. positive deep.

Experts believe that platypus, with their large tail and strong legs, must travel hundreds of kilometers of high seas to reach the continent, by rafting on debris, floating or swimming.

“Sherlock Holmes said, once you eliminate the impossible, whatever remains, however unlikely, must be true,” said Longrich. “It’s impossible to walk to Africa. These dinosaurs evolved long after continental drift separating continents and we have no evidence of land bridges. Geology tells us. Africa is isolated by the oceans. If so, the only way to get there is Water. “

Studies have shown that mammals, including monkeys and rodents, have made long and dangerous cruises from continent to continent before.

However, a team of researchers, led by the University of Bath along with researchers from Spain, the US, France and Morocco, believe that this is the first time that dinosaurs are believed to have made a great journey. positive.

The findings were published in the journal Cretaceous Research.
