Image: Fossil: Shundong Bi; Artwork: Zhao Chuang Paleontologists in China have unearthed the fossil of an oviraptorosaur sitting on a nest of eggs. By itself that’s an amazing and rare discovery, but this fossil is unique in that the eggs still preserve evidence of the unhatched progeny inside. Advertisement “Here we report the first [non-avian] dinosaur fossil known to preserve an adult skeleton atop an egg clutch that contains embryonic remains,” declare the authors of a research paper published in Science Bulletin. Found in China, the fossil is expanding our understanding of oviraptorosaur behavior and physiology, while providing further proof that non-avian dinosaurs employed bird-like brooding behaviors.
