Siberian locals have discovered an incredible prehistoric time capsule in what paleontologists believe is the largest ancient hyena lair ever found in Asia. The cave contained a whole menagerie of animal bones that had been undisturbed for about 42,000 years.
Paleontologists found the bones of both predator and prey animals from the Pleistocene epoch (2.6 million to 11,700 years ago), including brown bears, foxes, wolves, mammoths, rhinos, yaks, deer, gazelles, bison, horses, rodents, birds, fish and frogs.
