Similar to T.rex, Paleontologists Discover New Dinosaur Species in Argentina

Similar to T-Rex, paleontologists have discovered a new species of dinosaur in Argentina

Paleontologists in Argentina have discovered a new species of dinosaur with short arms such as Tyrannosaurus rex or T. rex.

The fossil of a new species called Meraxes gigas was found in northern Patagonia, Argentina.

According to research published in the journal Current Biology recently, this ancient creature was 11 meters long and weighed more than 4 tons.

Cited by CNN, Meraxes gigas are carnivores of the Carcharodontosauridae group of dinosaurs that lived in the Cretaceous period, 145 million to 66 million years ago.

Several fossils of Carcharodontosauridae have been found in the past 30 years, but little is known about its skull, forearms, or legs. However, this changed with the discovery of M. gigas due to its intact fossils.

“For the first time we know so many details about certain parts of the anatomy of this giant carnivorous dinosaur,” Juan Canal of the Ernesto Bachmann Museum of Paleontology in Neuquén, Argentina, told CNN.

The researchers found nearly intact forelimbs, making it easier for researchers to conclude that M. gigas had small shoulders, like T. rex.

But the team says that M. gigas lived far from T. rex and became extinct nearly 20 million years before T. rex walked on Earth.

Although these two types of dinosaurs had small heads and shoulders, Kanal said, their bone structure was very different.

The ancestors of M. gigas had longer shoulders and smaller heads and shoulders that were important in the hunting process but changed over time.

Researchers do not know if this fossil was a male or female dinosaur.
