For decades, the sandstone in central Australia yielded tantalising segments of some sort of fossil fish. Now, we have finally pieced together a complete picture of this remarkable species.
New research on the Late Devonian extinction suggests the ozone layer could be naturally depleted as the temperature rises.
The arrangement of bones in our specimen’s fins are the same as those of ‘fingers’ in tetrapods. The only difference is the digits are locked within the fin, and not free moving.
Remains of a 365m-year-old forest of extinct lycopsid trees has been found in China.
A record of sea-level change from 400 million years ago in South Africa, reveals how ecosystems and environments collapsed at the South Pole.
The discovery of two separate fossils tetrapod species proves that they lived all over the world by the end of Devonian.
Cladoxylopsid trees were hugely complex and very different to those we have now.
