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 first African fossils of Devonian ...

One of the best-documented evolutionary transitions is the appearance of tetrapods, the four-limbed vertebrates that now dominate the land. A large series of “fishapod” fossils have been discovered ...

The discovery of the first tetrapod fossil in Asia has dramatically expanded the range of these early four-legged creatures and could rewrite the books on their evolution. The incomplete left mandible ...

Some of our ancestors had four legs, a finned tail and lived in water. They were aquatic tetrapods which, after the end of the Devonian period 359 million years ago, increasingly moved onto the land.

I love outdated museum displays. They marvelously represent the “history” part of natural history exhibits – dusty dioramas of old ideas that are a baseline for how much our understanding has changed.

NOVA: What exactly is a tetrapod? Clack: A tetrapod is an animal with four legs—you, me—or an animal whose ancestors had four legs. So I can talk about a frog, which jumps; a bird, which flies; a ...

“I’m stunned,” Per Ahlberg, a paleontologist at Uppsala University in Sweden who coordinated the study, said in a statement. “A single track-bearing slab, which one person can lift, calls into ...
