In new research which was performed by the team of scientists at the Vyatka Paleontological Muesuem at Kirov in Russia and the North Carolina Muesuem Sciences at Raleigh in the USA has discovered two fossilized remains of species which belongs to the ancient saber-toothed predators. The remains of the long extinct species usually gave clues to the researchers who are involved in this study about the origination of mammals on the Earth.
These newly discovered fossil remains of the two predators which are a part of the collection of the Vyatka Paleontological Muesuem in Russia have given knowledge to the researchers about the period of the gap which is in the first mammal evolution. This gap which was discovered is said to very important as it is a period of significant mass extinctions which was specific functionalities due to some carnivores altered rapidly.
The fossils which were discovered are said to be of Permian Period, and they are said to have existed outside South Africa. The researchers who are involved in the study said that one of the fossil remains belongs to Nochintsageminidens and the other fossil belongs to the Gorynychusmasculine. These species are said to be small carnivore that have narrow pointed teeth, and they have a long snout. Their size is similar to that of wolves, and they are known to be the biggest predator of the region where they live.
The living mammal has originally originated from therapsids, and this animal group includes protomammals. Protomammals formed an important part of the terrestrial ecosystems which is during the Permian Period, and it dates back to nearly 229 to 252 million years ago. This period shows that they are before the oldest dinosaurs. These species consist of saber-toothed predators, tusked herbivores, and burrowing insectivores. These therapsids are discovered somewhere in South Africa’s Karoo Basin. Due to this reason scientist’s knowledge about them are only focused on South Africa region.
The study and its observation are published on the PeerJ journal.
