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 lack of large numbers of fossils makes it hard to study sexual dimorphism in dinosaurs. But a new statistical approach offers insight into this question and others across science.

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.
Genyornis newtoni was one of the biggest birds ever to walk the earth. And new research shows its mysterious extinction may have come amid a bout of widespread bone disease as its lake home dried out.
We studied 8,000 primate teeth and finally confirmed that humans are not the only living primate to suffer from cavities. But there are interesting differences.
A 5-million-year-old fossil that sat collecting dust in a Melbourne museum for more than a century has rewritten the evolutionary history of turtles in prehistoric Australia’s tropical climate.
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.
Homo bodoensis was named after a skull discovered almost 50 years ago in Ethiopia.

If scientific research is to take decolonization seriously, names for species should reflect this approach and consider the political, social and emotional implications.

The anatomy of the teeth in the cranium and its bones show that it belongs to an extinct cousin of the living African savanna and forest elephants.
With four tiny legs and an extraordinarily long body, a fossil of the snake-like lizard Tetrapodophis amplectus has created controversy.

In 2015, a published article described the fossil of a four-legged snake. New research has revealed that it is in fact a lizard, and the fossil is the centre of a scientific ethics debate.
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.
Studying these deposits gives scientists information about how past environments change. That, in turn, gives us informed estimates on how climates and environments will change in the near future.
A recent fossil discovery in the Mackenzie Mountains, NWT may change how we consider animal evolution.

Fossilized comb jellies, or ctenophores, are rare because the creatures are almost completely soft-bodied. Rare fossil finds are helping us learn more about ancient animals and evolution.
