Ancient forest found at bottom of huge sinkhole in China

An ancient forest has been found at the bottom of a giant sinkhole in China, with trees up to 40 metres (130ft) tall. Scientists believe it could contain undiscovered plant and animal species. Cave explorers in the Guangxi region of southern China alerted scientists when they found the sinkhole, which had a primitive forest inside. Among 30 sinkholes in Leye County this is the largest, at 306 metres long, 150 metres wide and 192 metres deep. An aerial photo shows a different karst sinkhole in Leye County in 2020. Photograph:…
