A multinational team of researchers has announced a first for the world of paleontology:a dinosaur preserved sitting atop a nest of its own eggs that include fossilized babies inside.The scientific paper describing the discovery was recently published in the journal Science Bulletin.The primary authors are Dr.BI Shundong,professor at Indiana University of Pennsylvania and XU Xing,paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology(IVPP),Chinese Academy of Sciences(CAS)in Beijing.The research team also includes CMNH co-interim director and lead dinosaur paleontologist Dr.Matt Lamanna.
