A nesting dinosaur
Article Abstract:
A recently discovered oviraptor fossil specimen reveals the presence of an avian type nesting behavior in oviraptorids. The specimen was collected in 1993, at Ukhaa Tolgod, South Central Mongolia. The vertebrae, tail, dorsal pelvic bones and skull are absent in this specimen but the gastralia and ribs are intact. The eggs are present in a circular pattern and each egg is 18 cm long and 6.5 cm broad. The presence of metacarpals I and II indicate the maniraptoran affinity of the specimen.

A basal tyrannosauroid dinosaur from the Late Jurassic of China
Article Abstract:
A new basal tyrannosauroid from the lower Upper Jurassic of the Junggar Basin, northwestern China is the oldest known tyrannosauroid and has several unexpectedly primitive pelvic features. It has a large, fragile and highly pneumatic cranial crest that is among the most elaborate known in any non-avian dinosaur and could be comparable to some classical exaggerated ornamental traits among vertebrates.
