ONE of the best-preserved fossils ever found confirms that young dinosaurs burst from their shells just like baby birds. Scientists on Tuesday announced the discovery of a dinosaur embryo from at least 66million years ago that was preparing to hatch from its egg.

University of Birmingham researcher Fion Waisum Ma, who co-authored a paper in the journal iScience, told AFP. Ma and colleagues found Baby Yingliang's head lay below its body, with the feet on either side and back curled — a posture that was previously unseen in dinosaurs, but similar to modern birds. In birds, the behavior is controlled by the central nervous system and called ...tucking.... Chicks preparing to hatch tuck their head under their right wing in order to stabilize the head while they crack the shell with their beak. Embryos that fail to tuck have a higher chance of death from an unsuccessful hatching. ...This indicates that such behavior in modern birds first evolved and originated among their dinosaur ancestors,... said Ma.

Oviraptorosaurs, which means ...egg thief lizards,... were feathered dinosaurs that lived in what is now Asia and North America during the Late Cretaceous period. They had variable beak shapes and diets, and ranged in size from modern turkeys at the lower end to massive Gigantoraptors, that were eight meters (26 feet) long. Baby Yingliang measures around 27 centimeters (10.6 inches) long from head to tail, and lies inside a 17 centimeter-long egg at the Yingliang Stone Nature History Museum. Researchers believe the creature is between 72 and 66 million years old, and was probably preserved by a sudden mudslide that buried the egg, protecting it from scavengers for eons. It would have grown two to three meters long if it had lived to be an adult, and would have likely fed on plants. The specimen was one of several egg fossils that were forgotten in storage for decades. The research team suspected they might contain unborn dinosaurs, and scraped off part of Baby Yingliang's egg shell to uncover the embryo hidden within. ...This dinosaur embryo inside its egg is one of the most beautiful fossils I have ever seen,... said Professor Steve Brusatte of the University of Edinburgh, part of the research team, in a statement. ...This little prenatal dinosaur looks just like a baby bird curled in its egg, which is yet more evidence that many features characteristic of today's birds first evolved in their dinosaur ancestors.... The team hopes to study Baby Yingliang in greater detail using advanced scanning techniques to image its full skeleton, including its skull bones, because part of the body is still covered by rock.
