Embryos that fail to tuck have a higher chance of death from an unsuccessful hatching.&quot;This indicates that such behavior in modern birds first evolved and originated among their dinosaur ancestors,&quot; said Ma.An alternative to tucking might have been something closer to what is seen in modern crocodiles, which instead assume a sitting posture with the head bending upon the chest up to hatching.<ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/spotlight/04/16/21/like-godzilla-but-actually-real-study-shows-t-rex-numbered-25-billion">‘Like Godzilla, but actually real’: Study shows T. rex numbered 2.5 billion</a></li></ul>FORGOTTEN IN STORAGEOviraptorosaurs, which means &quot;egg thief lizards,&quot; 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&#x27;s egg shell to uncover the embryo hidden within.&quot;This dinosaur embryo inside its egg is one of the most beautiful fossils I have ever seen,&quot; said Professor Steve Brusatte of the University of Edinburgh, part of the research team, in a statement.&quot;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&#x27;s birds first evolved in their dinosaur ancestors.&quot;<ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/spotlight/09/11/21/flying-dragon-dinosaur-roamed-southern-skies-scientists">&#x27;Flying Dragon&#x27; dinosaur roamed the southern skies too, scientists say</a></li></ul>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.<figure class="op-interactive"><iframe allow="autoplay; fullscreen" frameBorder="0" height="100%" id="ivsplayer01" scrolling="no" src="https://player.ivideosmart.com/ivsplayer/v4/dist/html/iframe-src.html?iframeid=ivsplayer01&amp;key=e8c22c015ca9eafa76f1e3edfa03c603&amp;spid=3001339&amp;vid=1756337" width="100%"></iframe></figure><div class="iwantbar">Watch more in <a href="//www.iwantv.com.ph/">iWantv</a> or <a href="//tfc.tv/">TFC.tv</a></div><div>RELATED VIDEO</div>
