The large fish, spanning nearly a metre on the lake bed, lived in waters thick with rival fish, including giants several ...

“This new fossilized trackway that we examined came from the early Carboniferous period, and it was significant for us to accurately identify its age – so we did this by comparing the different fish ...

Early Trade: The Money Cowrie When asked to picture “money,” most people think of paper bills, coins or simply numbers in a bank account. But in ancient times many would have thought of snails.

65 miles southwest of Chicago, a small hill that looks like a prop from an Indiana Jones contains many of the world's best-preserved, most diverse fossils.

The new study pushes the origin of amniotes much deeper into the Carboniferous Period, 299 million to 359 million years ago, which allows a much greater length of time for the diversification of ...

Amniotes are thought to have diverged from amphibians at the dawn of the Carboniferous period, about 355 million years ago. Mammals would diverge from reptiles and birds only 30 million years later.

If amniotes had already evolved by the earliest Carboniferous, as our fossil shows, the last common ancestor of amniotes and amphibians has to lie much further back in time, in the Devonian period.

Acanthostega, an early tetrapod that lived about 365 million years ago, was a member of the ancestral stock that gave rise to amphibians and amniotes. Image credit: supplied by authors Most scientists ...
