About 250 million years ago, on the border between the Paleozoic and Mesozoic, the Earth suffered the worst extinction in history, causing more than three-quarters of life loss. However, if some animal groups almost disappear completely, others are barely affected. According to the bones of small lizards from Antarctica, reptile is the last batch.
On the branches of the paracrocko East Tree: It may be the animal shadow lifestyle
Massive Perm extinction, which is called mass extinction, resulting in the huge collapse of biosphere , destroying about 70% of terrestrial species and 95% of marine species. From the smallest Flaminefer to the largest terrestrial vertebrates, all life was affected, but death did not kill all life day and night, and individual animal groups were relatively healthy in planetary disasters
Fortunately, the future overlord of the earth was reptiles: their losses were relatively small, and after their extinction, they soon began to fill the empty ecological geckos. But this is what a new ecosystem looks like since its extinction, and scientists haven't known it for a long time.
They now discover this by studying small reptile Palacrodon fossils found in the United States, South America and Antarctica. It was in Antarctica that paleontologists discovered the most intact specimens, and through ct scanning and microscopy, they were able to study it in detail.
This mysterious lizard, which was unable to determine its location for a long time, was discovered by relatives of the current dragon (Sauria). Scientists also found that Palakroton's teeth were used to eat plants, and the construction of his fingers implies a way of life for wood—only two million years after the mass extinction, the planet's vegetation is still recovering from shock.

So, in the first few million years later, reptiles began to live a wooden life and eat green food, which meant that the recovery of vegetation was relatively rapid. Perhaps the rebirth of life on Earth begins at the poles where the climate is milder and wetter, from where plants and animals have re-transmitted throughout the Earth.
