    Scientists have figured out why big carnivorous dinosaurs had small front legs

    Paleontologists have discovered a new species of dinosaur, which led them to the idea that tiny forelimbs did not play a very important role, but predators needed it.

    Scientists have discovered a new species of dinosaur, which they have named Meraxes gigas. This species got its name from the dragon Meraxes from the Game of Thrones series. This large carnivorous dinosaur belongs to a family of dinosaurs called carcharodontosaurids. And this find is the most complete skeleton of a representative of this family of all discovered by paleontologists. Thanks to this find, scientists have offered their explanation for why such large carnivorous dinosaurs had such small forepaws, according to SciTechDaily.

    Scientists have found the remains of a new carnivorous dinosaur in Argentina. They found a skull 1 meter long, femurs, as well as bones of the forelimbs 50 cm long and bones of his lower limbs. In total, this dinosaur had a length of 11 meters during its lifetime and weighed about 4 thousand kilograms. As for the period of his life, scientists believe that Meraxes gigas lived in what is now Argentina about 90-95 million years ago.

    According to scientists, the body anatomy of the new dinosaur is very similar to the body structure of a tyrannosaurus rex, although they were unrelated species. During the study of different huge predatory dinosaurs, scientists came to the conclusion that they went through the same evolutionary processes. At this time, their skull increased significantly in size, while the front legs became very small compared to the huge body.

    “Scientists are still arguing about why these large carnivorous dinosaurs had such small upper limbs. We have our own theory. Perhaps initially these paws played some important role in the extraction of food. But over time they atrophied to such sizes from “because the huge head, with the help of a large mouth, performed the functions of capturing the prey more effectively. The upper limbs began to play a secondary role, since now dinosaurs could cope with large prey only with the help of their jaws,” says Peter Makovitsky from the University of Minnesota , USA.

    But at the same time, scientists believe that the upper small paws of large bipedal predator dinosaurs could be needed during mating, when the male with with their help he kept the female. Scientists also believe that, given the size of the forepaws, which is half the size of the head of Meraxes gigas, this predator could not reach the jaws with them.

    “Usually, animals die out when they adapt too slowly to the environment environment. But here we see signs of a very rapid evolution, and yet the representatives of this family disappeared after several million years of living on Earth. We still do not know why this happened, “says Makovicki.

    As already wrote Focus, scientists have unraveled the secret of the dominance of dinosaurs on Earth.

    We also remind you that for the first time scientists have found a fossilized dinosaur egg inside another egg.
