New dinosaurs have tiny arms

Argentine experts have discovered an almost intact fossil skeleton of a new dinosaur standing on both legs and tiny arms of the Jurassic period, AFP quoted a leading paleontologist as saying on the 24th. / 5.

The newly discovered dinosaur belongs to the Abelisaurus family, which consists of carnivorous dinosaurs living in the southern hemisphere during the Cretaceous, about 70 to 100 million years ago, according to paleontologist Diego Pol.

"But the fossils we found are about 170 million years old," said Diego Pol in the early Jurassic period.

The new fossil found it to be quite a dinosaur similar to the tyrant dinosaur (Tyrannosaurus rex), but has smaller arms.

The newly discovered species, named Eoabelisaurus mefi , was identified before the oldest known species of the Abelisaurus family for more than 40 million years.

Unlike its descendants, the Eoabelisaurus mefi is six meters long, completely shrinking its arms with tiny claws. This shows that it only uses sharp iron teeth to hunt to feed itself, said paleontologist Diego Pol.

According to AFP, fossils of the Abelisaurus family are found in the southern hemisphere. Researchers believe that the vast desert in Pangea, the supercontinent of the fry before drifting into continents, has become the geographic wall that prevented the Abelisaurus dinosaurs from migrating to the ground. north.

The newly discovered fossil was found on the Condor hill, in the southern region of Chubut province, about 1,800 km southwest of Buenos Aires, the capital of Argentina.

A group of 25 members of the Edigio Feruglio Paleontological Museum in Chubut discovered fragments of fossils of the skull and spine of Eoabelisaurus mefi during an excavation in 2009.

Later, they were forced to stop excavation to avoid the winter and resume their work the following summer, to dig almost the entire fossil skeleton of this carnivorous dinosaur, the paleontologist learn Diego Pol said.
