Dinosaurs built on ducks crossed the ocean to go to Africa

Ancient researchers report that a hydrosore or “dinosaur built from a duck” was discovered in Africa. This interesting preview gives us an even more interesting idea of ​​how these dinosaurs could cross the ocean and reach this continent.

The most common ornithopod dinosaur family, the Hatrosuridae, also known as “duck-shaped dinosaurs”, is extinct. We know from fossils that these creatures originated in North America before spreading across land bridges to South America, Asia and Europe.

Ancient researchers announced today the discovery of the remains (teeth and jaws) of one of these animals. It is 66 million years old and refers to a new species called Ajnapia odysseus. It is special? It was discovered in Africa. However, we know that at that time the African continent was isolated from sea routes.

“It’s like finding a kangaroo in Scotland.”
The new fossil was discovered in a mine just hours from Casablanca, according to Dr Nicholas Longrich of the Milner Center for Evolution at the University of Bath, who led the study. “It’s like finding a kangaroo in Scotland.”

Quoting Sherlock Holmes, the researcher continues: “If you leave the impossible, the impossible is real”. “Then we just realized. These dinosaurs actually formed long after continental drift divided continents and we have no evidence of the existence of land bridges. “

A cross in swimming or on rafts
The big question is: how did this dinosaur, about three meters long, get there?

“Considering the existence of large continuous sea lanes that isolate Africa and Europe from other continents and the lack of full bi-directional transmissions representing land bridges, these models are the waterfalls we have studied in the study of reptiles, reptiles and so on. Street.

According to archaeologists, this and other specimens can be reached by swimming on African beaches in the open sea or by climbing garbage rafts.

The first hypothesis is valid. Indeed, as the researcher points out, these broad-tailed, stout-footed dinosaurs can be good swimmers. Furthermore, many related bones have been isolated in river deposits. However, he points out that these animals had to travel hundreds of kilometers before reaching the shore.

The second hypothesis is also interesting. Sea smuggling on rafts of debris is rare but has been documented. Green iguanas traveled between islands in the Caribbean due to a hurricane. The ocean sections also explain how lemons and hippos got to Madagascar, or how monkeys from Africa crossed the Atlantic to South America.
