Buenos Aires | the remains Of a new species of small carnivorous dinosaur with wings, that lived in Patagonia, there are 90 million years ago, have been discovered in Argentina, announced Thursday that paleontologists, who estimate that this specimen may yield information on the evolution of birds.
The remains of the animal, which did not exceed the meter and a half long, were found on a website of the province of Rio Negro (center), about 1100 km south of Buenos Aires, according to the Agency of scientific dissemination of the national University of La Matanza.
This new species has been named Overoraptor chimentoi and it belongs to the group of carnivorous dinosaurs called Paraves, explained Matias Motta, a researcher at the Museum of argentine natural sciences (macn is).
The first findings date back to 2013, and then, during a second campaign in 2018, other remains were found.
“This animal had a claw very lot on his index finger, which he used as probably to attack its prey. He also had a long-legged which indicates that it was an animal that would be,” said Mr. Motta, the lead author of a study published in the journal The Science of Nature.
According to Mr. Motta, “this animal belongs to a new group of dinosaurs of the southern hemisphere, it was certainly fast, agile, and like its congeners, it had to be a carnivore”.
The scientists were astonished to observe that the legs of this specimen were similar to those of a raptor, while the upper part (of the legs) was robust and elongated, similar to that of modern birds, they explained.
Until this find, all carnivorous dinosaurs with a bird aspect discovered in Patagonia belonged to the group of Unenlagia, they were agile and walked on their hind legs.
“On the contrary of what we thought at the beginning, the Overoraptor is not part of the family of Unenlagia, but another group that includes a species from Madagascar called Rahonavis”, explained the paleontologist
