“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 found a massive ancient forest hidden inside a giant sinkhole in China’s Guangxi region, Xinhua News reported.
The sinkhole measured over a thousand feet in length and was nearly 630 feet deep, Zhang Yuanhai, a senior engineer with the Institute of Karst Geology at the Chinese Academy of Geological Sciences, told the outlet earlier this month.
The explorers rappelled down more than 328-feet into the sinkhole before trekking for several hours to reach the bottom. On the sinkhole floor, they found a primeval forest with ancient trees 130 feet tall, expedition team leader Chen Lixin told Xinhua. He added that the plants grew densely together and came up to his shoulders.
A Twitter video dated May 7 showed expedition team members climbing through the dense foliage and operating a drone to document the sinkhole.
