Starfish are one of the most recognisable animals on our planet.
New study sheds light on how the starfish evolved.
Kate Winslet plays palaeontologist Mary Anning in the film Ammonite. The love story may be fictional — but how does the science stand up?
Megalodons are the biggest predatory sharks ever discovered.
New fossil detective work sheds light on the life of megalodon, the biggest predatory shark ever discovered.
The research site at the Olduvai Gorge.
The research shows that 2 million years ago humans were not constrained technologically and already had the capacity to expand their geographic range.
Crocodiles have not evolved much in the past 200 million years.
New research shows crocodiles have landed upon an equilibrium state of evolution.
Whether in the wild or in the lab, worms have an interesting story to tell.

'Worm' is really a catchall term for a huge variety of animals with different characteristics that span the tree of life. They hold clues about our own origins as well as hints about human health.
Many species of iguanas dig shelters for protection against predators, fires and extreme weather. Most also make underground nests.

A trace fossil of an iguana burrow was discovered on San Salvador Island in the Bahamas. Estimated to be 115,000 years old, it is the first known fossil of its kind.
Ancient fatty molecules, once believed to be traces of some of the first animals to live on Earth, may have been produced by algae instead.

A war with Neanderthals makes a compelling narrative but the evidence is limited is best.

If albanerpetontids were around today, they'd easily fit in your hand. And although their bones are found all over the world, these unique amphibians eluded experts for a long time.
Cimoliopterus pterosaurs, with 5m wing spans.

Fossils reveal that dinosaurs' flying cousins become twice as efficient at flying over 150 million years.
Fossil remains indicate these birds had a wingspan of over 20 feet.
Paleontologists have discovered fossil remains belonging to an enormous 'toothed' bird that lived for a period of about 60 million years after dinosaurs.
Drilling 139 meters down to volcanic rock provided scientists with a million-year environmental record.

A new environmental record for a prehistoric site in Kenya helped researchers figure out how external conditions influenced which of our ancient ancestors lived there, with what way of life.

New study used X-rays of the teeth of early mammals' to show they were more like cold blooded reptiles.
These fossil trackways resemble the tracks left by flamingos today, but are bigger. Just above the scale bar one can see (more faintly) the ‘tramline traces’ made by the ancient birds’ stomping action.
One avian track, probably made by a large gull or a small goose, was found in sediments that have been dated to about 400,000 years. That makes it the oldest avian track reported from southern Africa.
Artefacts suggest a ‘great leap’, a recent evolution of modern intelligence. Fossils and DNA argue that’s an illusion.
You can gauge a dinosaur's body mass either by reconstructing it as accurately as possible, or by scaling its leg bones against those of today's animals. Research shows both methods work well together.
New research show how crinoids could live for so long on floating wood without it breaking up.
