Today, Antarctica is a huge frozen continent, though it was once temperate enough to be covered in swampy forests. Now, a team of scientists has discovered fossilized tree resin—amber—on the continent for the first time.

Along with fossils of roots, pollen, and spores, the amber provides some of the best evidence yet that a mid-Cretaceous, swampy rainforest existed near the South Pole, and that this prehistoric environment was " dominated by conifers ", similar to forests in New Zealand and Patagonia today.

The amber, excavated from Pine Island Bay in the Amundsen Sea Embayment, provides a unique snapshot of life in prehistoric Antarctica.
