Kirkdale Cave

Kirkdale Cave is a cave and fossil site located in Kirkdale near Kirkbymoorside in the Vale of Pickering, North Yorkshire, England. It was discovered by workmen in 1821, and found to contain fossilized bones of a variety of mammals from the Eemian interglacial (globally known as the Last Interglacial, ~130-115,000 years ago), when temperatures were comparable to contemporary times, including animals currently absent from Britain or globally extinct, including hippopotamuses (amongst the farthest north any such remains have been found), straight-tusked elephants, the narrow-nosed rhinoceros, and cave hyenas.
