Using environmental DNA analysis and traditional fishing techniques, researchers are seeking answers about the current population of axolotls in their natural habitat. The numbers are alarming.

They're quite literally under a lot of pressure

The genetic switch that 'really lets horses have their cake and eat it too.'

A species of houndshark called Mustelus lenticulatus makes sharp clicking noises when handled. Until now, sharks as a group were thought to be universally quiet

Fossilized vulture feathers that were stunningly preserved in volcanic ash were a mystery until now.

Paleontologists from the Australian Museum Research Institute, the University of New South Wales, the University of Canberra and CSIRO have described a new species of osmeriform fish from the fossilized remains found in New South Wales, Australia.

The find has provided the first detailed evidence in Australia for a group of fish called the Osmeriformes, which today include graylings and smelts

Ancient iguanas sailed around 5,000 miles from North America to Fiji by clinging to floating vegetation, new research suggests.

The new study could also offer important clues into human evolution.

Tropical riparian ecosystems in what is now North China recovered within as little as 2 million years after the end-Permian extinction, one of the most devastating bio-crises in the history of life, destroying both marine and terrestrial ecosystems.

Bastetodon, a leopard-like apex predator, probably dined on early forms of primates, hippos, and elephants.

Learn more about the discovery of megaraptorid and carcharodontosaur fossils that shake up Australia's Cretaceous predatory hierarchy.
