An abandoned oil-shale pit near Frankfurt that was nearly turned into a landfill and is now a UNESCO World Heritage site, because the black shale preserves complete animals: bats with their last meal identifiable, horses the size of a terrier with unborn foals, beetles that still show structural colour, a pair of turtles fossilised while mating. Preservation quality is arguably the best on Earth for its age. LOOK ONLY; guided tours from the visitor centre.
