Fossilised rainforest dating back 90-million-years discovered underneath Antarctic ice

Researchers have reportedly discovered 90-million-year-old fossilized remains of a rainforest underneath Antarctic ice which reveals that continent was warmer than what it is today. finding suggests that forests in Antarctica resembled present-day forests of New Zealand during  mid-Cretaceous geographical period, over 145 million years ago. While it has been discovered that period was  warmest in 140 million years, sea level was 170 meters higher.

According to reports, study concluded its findings based on evidence from sediments collected at seabed near Pine Island glacier in west of Antarctica. samples taken in year 2017 revealed about environmental condition of  Antarctic Polar Circle. A geologist at Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research in Germany, and study’s first author Dr. Johann Kls, told a media outlet that scientists studied well-preserved diverse fossil pollen and or plant remains in sediment deposited some 90 million years ago near South Pole. He said that preserves in sediment indicated that  coast of West Antarctica was actually a dense temperate, swampy forest.

Higher carbon dioxide levels

scientists studied depth of roots preserved in core of sediment to discover  Antarctic’s past environments and climates. y n constructed a photograph of its landscape from millions of years ago. To achieve this, y CT-scanned soil, as per media reports. According to study, evidence of a mild climate has been found around 500 miles from South Pole, with annual mean temperatures of around 12°C and summer temperatures averaging at 19°C.

study also found that rainfall recorded in region was similar to UK’s Wales region. refore, scientists inferred that Antarctica h climate similar to UK 90 million years ago than what it has w, temperature ranging from -10°C to -60°C at its highest point. It was also discovered that  carbon dioxide levels in Antarctica's atmosphere millions of years ago used to be significantly higher.
