German researchers found amber in Antarctica for the first timeace666, proving it had trees 90 million years ago.
In 2017, the Alfred Wegener Institute scientists found it from a depth of 946 meters using the MARUM-MeBo70 seafloor drill.

— Gizmodo (@Gizmodo) November 16, 2024The scientists found amber on six of Earth’s seven continents before the Antarctic discovery. It’s the first amber found at this extreme latitude, confirming that the region once supported resin-producing trees.
Resin is a thick liquid that oozes from trees. Eventually, it solidifies after an extended period into a yellow crystal called amber.

Dr. Henny Gerschel, a consultant at the Saxon State Office for the Environment, Agriculture, and Geology, said the tests revealed new details regarding the amber:

The AWI website says the team will test the sample further. Success should reveal even more clues about the ancient Antarctic environment that supported resin-producing trees.
“Our discovery is another piece of the puzzle and will help us gain a better understanding of the swampy, conifer-rich, temperate rainforest environment identified near the South Pole during the mid-Cretaceous,” said Gerschel.

The team hopes to find even more samples to complete the picture of this ancient forest ecosystem.ace666
