A thick layer cake of strata in northeastern China's Liaoning Province has attracted worldwide attention as a mother lode of fossils casting light on the state of life here 130 million to 110 million years ago. The most spectacular discoveries have been several species of feathered dinosaurs, creatures that have bolstered the theory that birds descended from dinosaurs. Yet the site has also yielded a trove of other fossils, including birds, insects, mammals, fish, amphibians, pterosaurs, and plants preserved in layers of shale, mudstone, and volcanic ash.
