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 ...

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

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

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 ...

While we haven’t yet found any tetrapod bone fossils from the Early Devonian, it’s likely they first evolved in this period. The first tetrapods likely evolved from Elpistostegalia, a group of ...

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.

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 ...

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.
