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.

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 first tetrapods evolved from fishes during the Devonian period, which ended about 360 million years ago. For many decades, our idea of what Devonian tetrapods were like have been based on just ...

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.

Devonian-era lungfish may have faked us out, left tetrapod-like tracks The modern relatives of the fish that gave rise to vertebrates with four limbs … ...

He hoped to find some more material of a thing called Ichthyostega, which is the Devonian tetrapod that most people have heard of if they've heard of Devonian tetrapods. It's the one often ...
