Argentine paleontologists discover small carnivorous dinosaur

JUNE 4, 2020

Fossilized remains of a new species of dinosaur that lived 90 million years ago have been discovered in Patagonia, Argentine paleontologists announced on Thursday.

The winged dinosaur had legs similar to the velociraptor and experts believe it may hold the key to revealing information about the evolution of birds.

The fossil remains, which measure less than a meter and a half in length, were discovered at a dig in the province of Rio Negro in Argentine Patagonia, around 1,100 kilometers (685 miles) from Buenos Aires, the scientific dissemination agency from the La Matanza university said.

It is a new species of carnivorous Paraves theropod that has been named Overoraptor chimentoi, explained Matias Motta, a researcher from the Argentine natural sciences museum.

Argentine paleontologists reported the discovery in Patagonia of a new 90 million-year-old dinosaur species with raptor-like legs and wings, which could reveal data on the evolution and emergence of birds.

The fossil remains of the animal, which did not exceed a meter and a half in length, were found in a site in the Argentine province of Río Negro, some 1,100 km south of Buenos Aires, the scientific dissemination agency of the University of La CTyS slaughter.

It is a new species, named Overoraptor chimentoi , belonging to the group of carnivorous dinosaurs called Paravians, explained Matías Motta, from the Laboratory of Comparative Anatomy and Evolution of Vertebrates of the Argentine Museum of Natural Sciences .

In 2013 they made the first find and then, in a second campaign, in 2018 they found more remains.

"This animal had a very sharp claw on the index finger of its foot, which surely served to attack its prey, and had a long and graceful leg, indicating that it was a running animal," said Motta, lead author. from the study published in The Science of Nature .

According to Motta, "this animal turned out to belong to a new group of dinosaurs in the Southern Hemisphere; it was surely fast, agile and, like all its relatives, it would be carnivorous."

The researchers were surprised that the legs looked like those of a raptor, but its upper limbs were very long and robust, similar to those of modern birds, they explained.

The new dinosaur species is 90 million years old.
