An exceptionally well-preserved theropod dinosaur from the Yixian Formation of China
Article Abstract:
Farmers in Liaoning, China, discovered two almost complete skeletons of Sinosauropteryx, a dinosaur species closely linked with Compsognathus. The skeletons are from the basal part of the Yixian Formation, which has four fossil-bearing sedimentary intercalations. The skeletons are particularly interesting for their integumentary structures, which are extremely well preserved. There are no structures showing the basic morphological features of modern bird feathers, but they could be protofeathers which have not previously been identified.
