In a recent finding, scientists have unearthed South African fossils about the prehistoric Devonian Period amphibians which are believed to be the first four-legged vertebrates at a site which is known as Waterloo Farm in Grahamstown.
The two tetrapods fossils which are named as Tutusius and Umazantsia. As per the scientists, they have described them as the resembling cross between an alligator and a fish. These species are said to be amphibians and scientists have deduced that they will eat small fish and while in water and tiny vertebrate while they are on land. The discovered fossils have the importance, and they lie in an environment where they are unearthed.
These Devonian tetrapods are being known as all vertebrates, and the amphibious aquatic tetrapods are said to be first colonized on the land. As per scientist, their evolution takes place in warm tropical places. The South African fossils which are known as they also have present in colder environments and they are present on an Antarctic circle which was some 360 million years ago.
According to the paleontologists who are identified as Tutsis from the piece of the shoulder girdle bone and the species was estimated to be about 3 feet long and they have decided to name this species after Desmond Tutu who is the South African human rights activist. Umzanmtsia was measured to be about 2.3 feet long and have a slender lower jaw, and it also has small pointed teeth.
The fossils of Devonian tetrapod can be found everywhere in the world but they are not seen in ancient supercontinent like Gondwana, and in this present time they have become countries like India, South America, Australia Africa and Antarctica. The fossil which was found was a jaw and footprints that are in eastern Australia.
The lead author of the study, Dr. Robert Gess said that they came from localities which were present in tropical regions which were during the Devonian and these specimens lived within the Antarctica circle. The study was published in the journal Science.
