Ocucaje desert was a seabed 12 million years ago. But thanks to extraordinary dry climate and combination of specific metals and calcium it still looks like a seabed, just without water. Petrified corals, whales and even prehistoric giant shark with petrified teeth and brains.
Ocucaje is isolated landscape of loneliness and using some of your imaginations it feels like a planet from outer space. For me it is a iconic "Dune" by Frank Herbert.
