The previous world record holder in the longest sandstone cave category was Venezuela's Cueva Del Saman in Edo Zulia. This is an 18,200-metre (18.2km) long quartzite sandstone cave.
The dinosaur fossils in the longest sandstone cave in the world include those of the Mosasaurus.
It was a carnivorous aquatic lizard that resided on Earth around 66-70 million years ago.
