The fossil found on the lands of South Africa of tetrapods has shed some lights on the new data on the fact of a start of life on our planet. The discovery of the found fossils demonstrated that the four-legged vertebrates developed in any part of the world and not just in the tropical regions as suggested by the earlier studies.

Researchers have found the fossil in South African Land of pre-historic Devonian age. Till now the amphibians is supposed to be one of oldest four-legged vertebrates known located at a site in Grahamstown called the Waterloo Farm.

Tutusius and Umzantsia were the names of the two fossils found of the tetrapods. The researchers explained them as a species who is a cross breed of a fish and an alligator. The found species were categorized as amphibians, researchers mentioned they could eat tiny invertebrates while their trip on land and would have been eating small fish when they are in the water.

Devonian tetrapods are considered as the forefathers of all vertebrates, and being the amphibious, aquatic tetrapods who is first one to make their colony on the land. As per the earlier studies, these kinds of species were first evolved in the tropical regions.

Now, when it is about the South African fossils, the fact which has come out is that these species are once the residents of the colder places. To be specific, they are in the Antarctic regions somewhere around 360M years ago.

The paleontologists discovered the species of Tutusius through its shoulder girdle bone. The species was estimated to have the length of 3 feet. The researchers decided to give the name to the species after the human right activist from South Africa, Desmond Tutu.

On the other hand, Umzantsia, the other species measured around the length of 2.3 feet, has small pointed teeth and has a slender lower jaw.
