Researchers discovered that this “monster” managed to survive a mass extinction. The suborder Gorgonapsida was a group of animals that predated mammals. New fossils found indicate that they lived longer than expected for this type of species.

According to studies, this group of animals should have been extinct a long time ago, but they managed to live longer than expected. At the end of the Permian period, about 250 million years ago, the planet's biodiversity underwent changes that led to the extinction of practically 90% of the races that inhabited here. The fact occurred mainly due to a change in the environment, which changed a lot in a short time, which led to a global catastrophe. Until then, scientists believed that the Gorgonopsida had become extinct precisely during this catastrophe.
However, in recent discoveries through the discovery of new fossils, researchers' opinions may have changed. Fossils found in the Karoo Basin in South Africa show that this group managed to survive well into the Triassic period. The presented research suggests that these monsters, even after managing to survive the mass extinction, suffered consequences that led to their extermination even after many years.
Although they survived the extinction of their time, the group's lineage weakened over time and their demise led to their extinction, albeit belatedly. That phenomenon it is called extinction debt and occurs due to gradual changes in the ecosystems of the species.
These extinctions take about millions of years, but this group was able to survive longer. Because of this change in environment and changes in living beings that lived on Earth, they began to be charged for this "survival" being driven to extinction even so.
These monsters were part of the Synapsida class and later adapted to give rise to modern mammals.
