Discover the oldest cave in the world

Jenolan caves in Sydney's west have been identified as 340 million years old they become the oldest open caves in the world.

Dr. Armstrong Osborne at the University of Sydney, Australia, and colleagues used clay dating methods to show that these caves were opened from the Carbon century.

"These caves are hundreds of millions of years older than any other cave in the world previously reported," Osborne said. The oldest life of an open cave has been determined to date for 90 million years.

"Even geologically, 340 million years is an extremely long time. At the same time, Blue Mountain began to form 100 million years ago, dinosaurs extinct 65 million years ago and Tasmania was connected to continent nearly 10,000 years ago, " Osborne said.
