Bipedal movement has existed in modern reptiles for much longer than we previously knew.
Snakes have survived millions of years by using their bodies in increasingly creative ways.
A drying climate caused a mass extinction among plants, but paved the way for the ancestors of modern reptiles, mammals, and birds.
Turtles can’t head south for the winter, so they hibernate in rivers, lakes and ponds.
Crisp temperatures, ice-capped ponds and frozen landscapes send animals scurrying for cover. But just what do turtles do when winter takes hold?

A set of fossils that lay forgotten in a museum are revealing new secrets about Britain's prehistoric wildlife.
Boa constrictors are frequently found at large in Australia, despite being banned.
Keeping non-native reptiles as pets is against the law – with good reason. Alien species traded on the black market can potentially establish themselves in the wild if they are released or escape.

Mammals' ancestors had a third eye and the fossil record of its disappearance tells us the story of the evolution of one of our most important features: warm blood.
TV audiences cheered on the iguanas' escape, but won't somebody think of the poor snakes?
Just what the doctor ordered - more cane toads.
It sounds weird, but releasing small cane toads ahead of the main invasion front can help predators learn to avoid the biggest, most toxic ones. Here's exactly how it works.
Hey, is there something on my back?

Tiny animals along for the ride, called epibionts, could be used as living data-loggers. Researchers can glean info from them that could help inform turtle-friendly fisheries management decisions.
An anaconda peers above and below the water. Did snakes evolve on land or underwater?

One of the enduring controversies in evolution is why snakes evolved their long, limbless bodies. A new study suggests snakes may have lost their legs at sea, before crawling ashore.
There’s a battle for resources going on in there.
Embryos greedily want more resources than their fair share. New research investigates how early in evolution their hormonal tactics arose.

A new study of the first ever snake fossil with legs suggests that snakes evolved on land rather than in the ocean, as previously thought.
How many kangaroos is too many?
Each year rangers in the Australian Capital Territory cull kangaroos as part of the territory’s Kangaroo Management Plan. This year they killed a few over 1,500 kangaroos. Even though millions of kangaroos…
