Anchiornis is a genus of small, feathered, eumaniraptoran dinosaurs. The genus Anchiornis contains only the type species Anchiornis huxleyi. It was named in honor of Thomas Henry Huxley, an early proponent of biological evolution, and one of the first to propose a close evolutionary relationship between birds and dinosaurs. The generic name Anchiornis means "near bird", and its describers cited it as important in filling a gap in the transition between the body plans of birds and dinosaurs.
Anchiornis huxleyi fossils have been found in the Tiaojishan Formation of Liaoning, China, in rocks dated to the late Jurassic period ( Oxfordian age), 161.0–160.5 million years ago.
Given the exquisite preservation of one of the animal's fossils, Anchiornis huxleyi became the first dinosaur species for which almost the entire life coloration could be determined.
