It is not every day that scientists stumble on to a beautifully preserved ancient forest nestled deep inside a sinkhole the size of a large residential complex. Such a discovery was made in a stunning karst mountain range in Guangxi Zhuang autonomous region in south China when a team of explorers entered the 192-metre-deep sinkhole on May 6 and found.
"I wouldn't be surprised to know that there are species found in these caves that have never been reported or described by science until now," one researcher said.
Cave explorers in China discovered an unspeakably large sinkhole that contains an pristine and ancient forest practically untouched by human civilization.
