In Depth Yet another oviraptosaur from the late Cretaceous of Asia, the partial remains of Luoyanggia make it hard to establish an accurate size for the genus, though it is noted to be towards the smaller end of the oviraptosaur size spectrum. Luoyanggia is usually placed within the Oviraptoridae, the same assignment as the original … Read more
