A new giant carnivorous dinosaur is found

According to Argentina's "Corporation" on July 7th local time, the dinosaur fossils found in Batcondia, northern Argentine were identified as a new dinosaur species found so far. The head and shorter forelimbs are one of the largest carnivorous animals found so far. Biologists use one of the dragons in "Game of Thrones" to name them MERAXES Gigas.

The skull of MERAXES Gigas has a length of more than 163cm.

According to reports, MERAXES GIGAS lived in the Baiji period 93 million years ago. It was extinct 85 million years ago, with a length of 11 meters and a weight of more than 4 tons. Initial analysis died at the age of 45.

Experts said that this dinosaur has huge skulls and teeth, but the forelimbs are surprisingly short, almost the same as human arm, but its legs are very powerful, and the skull is far greater than the known bully of the Overlord Dragon.

The best preservation of MERAXES Gigas is its feet. The bone fossils are clear and complete, the bone density is extremely high, hard and powerful, and a solid ligament is connected in the middle. Experts said that this is to bear its huge weight evolution.

Another striking feature is that its inner finger claws are much larger than the other two outer finger claws (almost twice the long outer finger long), and the edge of the fingertips is slightly pointed. This feature is from other dinosaurs in the early days. It has not appeared, so so far, this is also a significant feature of this new species.

"MERAXES Gigas and Tyrannosaurus have great differences in evolution. There is no direct relationship between the two. The environment of his life is very different from the environment we see today. 93 million years ago, it was very humid and warm, and the vegetation was rich. "Juan Canale, the person in charge of the Argentine Museum of Museum of Poto, explained.

In addition, the researchers also found that there are some grooves and raised small horns on the skull of MERAXES Gigas. For researchers, this discovery is one of the most exciting moments in his career. Deep, so the maintenance situation is very good, without signs of severe erosion.

In response to the cause of this giant carnivorous dinosaur extinction, some experts analyzed that at the end of the Baiji period, a "small and non -large -scale extinction incident" occurred at the time, which may be due to the extinction of these top predators due to climate change, but it is currently not possible Sure.
