A holotype fossil was recently found in East China’s Fujian Province and described in the journal Nature. The pelvis, trunk, forelimbs, and part of the hindlimb are all intact.“Baminornis is a landmark discovery and ranks among the most important bird fossils unearthed since the discovery of Archaeopteryx in the early 1860s,” Stephen Brusatte, a paleontologist from the University of Edinburgh who was not involved in the study but wrote a commentary accompanying it, tells Xinhua.“This is a groundbreaking discovery.
