Two new species of saber-tooth predators have been discovered in Russia, which may help us better understand the evolution of mammals. The fossils, which were found near the town of Kotelnich, around the Vyatka River, in the part of Russia situated on the European continent.
The first of the fossils was given the scientific name Gorynychus Masyutinae, and it is a carnivore with a size similar to that of a wolf, and the other, smaller in size, was called Nochnitsa Geminidens, and is a kind of snout long. The two new species were given their names from legendary monsters of Russian folk wisdom because of their terrifying appearance.
This new discovery will help scientists to better understand the ancestral evolution of mammals following extinction during the Permian period some 260 million years ago, a period in which researchers believe that much of the ecosystem was dominated by creatures by saber-tooth predators, because after this period, carnivores of shorter stature began to dominate the Earth.
According to Christian Kammerer, who was responsible for the study, at this particular time, there was a kind of reversal of roles, in which small creatures became great and menacing beings, and creatures of great stature became tiny creatures.
According to the scientist, the region of Kotelnich is one of the most important regions in the world in terms of the fossils of this period, not only by its quantity, but also by its state of preservation and diversity.
