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 discovery of the fossil remains of a tetrapod-like fish sheds light on the order in which important tetrapod characters arose.

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 first African fossils of Devonian tetrapods (four-legged vertebrates) show these pioneers of land living within the Antarctic circle, 360 million years ago.

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.

Science 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 … John Timmer – Dec 14, 2011 5:57 ...

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 ...

Originally, the timeline for how this massive diversification of life occurred was fairly clear-cut. The first tetrapods evolved roughly 390 million years ago during the Devonian period.

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.
