A closer look at these fossil bones revealed more than the suggestion of a previously undescribed species - it pointed to the individual animal having suffered with osteoarthritis.
The largest animals to ever walk the earth, giant sauropods dominated world ecosystems for 100 million years. New research indicates soft ‘heel pads’ helped them reach their stature.
The mysterious Denisovans left DNA traces in populations across Southeast Asia and Australasia, but until now no physical signs of their presence outside Eurasia had been found.
Two newly discovered species of quokka-sized kangaroos, which lived 18 million years ago in the Queensland rainforest, show evolution in the act of giving kangaroos a taste for leaves.
The little dinosaur is curled up inside its shell the same way birds do before hatching, shedding new light on the link between the behaviour of dinosaurs and modern birds.
A new study finds more than one early human species lived on the landscape in Northern Tanzania 3.66 million years ago. But there are reasons to be cautious about the findings.
Most modern animals have their roots half a billion years ago in the Cambrian Explosion, but one group was curiously missing from the fossil record - until now.
The complex social behaviour in early dinosaurs observed in a new study lines up with other fossil evidence that dinosaurs were more bird-like than crocodilian-like.
