- Location: Northeastern China, mostly Liaoning Province Date: Early Cretaceous; late Valanginian - Aptian, 128-120 million years ago These fossil beds reveal a collection of organisms found around a prehistoric lake during the Early Cretaceous, some 125 million years ago. These fossil beds belong to a very rare type of preservation called lagerstatten, which preserves the fine details of flesh, fur, and feathers. In 1996, this formation and region became a scientific goldmine when the fossils of a dinosaur, Sinosauropteryx prima, was discovered with feathers. More feathered dinosaurs and unique animal fauna has been uncovered. So far, very few large animals get preserved.

It was not until the 1990s when remarkable fossils of birds and dinosaurs were excavated. Since 1996, a number of dinosaur fossils that have revolutionized our knowledge of these animals have been found at Yixian; among them are the first known non-avian theropods with feathers. Fossils found at Yixian include:
