Scientists from Rhodes University and Uppsala University have described two new species of four-legged animals that lived on Earth about 360 million years ago, shortly after the planet appeared the representatives of the superclass.

The remains were discovered in Africa, which in those days was part of the supercontinent Gondwana. It is noted that the area in which were found the fossils was at the Antarctic polar circle. Previously it was thought that tetrapods appeared in the tropical and subtropical climate and finding refutes this hypothesis.

During researches scientists have discovered fossils of the clavicle Tutusius umlambo and several of the skull bones and clavicle Umzantsia amazana. The remains found in southern Africa, in the town of Waterloo farm, which in the Devonian period, there were approximately 70 South latitude in the Antarctic region.

It is worth noting that the climate in Devon, apparently, was quite warm, the glaciers on the planet was not, and the difference between the temperature at the poles and at the equator was much less than now. But in the late Devonian-early Carboniferous period, the climate became more severe and occurred in the past. When it came to the place of the modern Waterloo farm, is unknown. But even if the ancient four-legged’t find him, they lived in a rather harsh climate and they had a few months to experience the polar night
