Explanation:

The world’s longest sandstone cave named Krem Puri has discovered near the village of Laitsohum in Mawsynram area of East Khasi Hills district of Meghalaya. With a length of 24,583 metres, Krem Puri was discovered back in 2016 but the actual length of the cave was obtained by the Meghalaya Adventurers’ Association (MAA) during one of its recent expeditions. Krem Puri is over 6,000m longer than the current listed sandstone cave in the world, Cueva El Samán, (18,200m) in Venezuela. The cave system has fossils of dinosaurs, especially the Mosasaurus, a giant reptile that lived 66-76 million years ago.
