The relationship of limbed vertebrates (tetrapods) to lobe-finned fish (sarcopterygians) is well established, but the origin of major tetrapod features has remained obscure for lack of fossils ...

Our new discovery, published today in Nature, details ancient fossil footprints found in Australia that upend the early ...

Newly analyzed jawbones from 380-million-year-old lungfish are shedding light on the feeding behaviors of our earliest ...

The first African Devonian tetrapods. Two new species, named Tutusius and Umzantsia, are Africa's earliest known four-legged vertebrates by a remarkable 70 million years.

So Devonian tetrapods have a long early history about which, until now, we have known very little. This is a frustrating picture, considering that we are dealing with one of the most important ...

The tetrapod’s forelimbs were very limited in their range of motion, the researchers found, and the hindlimbs of Ichthyostega would have been virtually useless for support on Devonian mudbanks.

In 2015, two members of the Blue Beach Fossil Museum in Nova Scotia found a long, curved fossil jaw, bristling with teeth.

Fossilized tracks in Australia reveal amniotes evolved 35-40 million years earlier than thought, pushing tetrapod origins back to the Devonian period.

The origin of four-limbed animals known as tetrapods was thought to be fairly straightforward: Fish flopped onto land in the Devonian, evolved, and eventually diversified into the reptiles, birds ...

The first tetrapods evolved roughly 390 million years ago during the Devonian period. Amniotoes and the earliest members of the modern groups of animals we see today followed fishapods during the ...
