Dinosaurs still exist...science prediction.
Birds evolved from dinosaurs? Scientists got more evidence. Check this amazing fossil of a baby dinosaur curled up inside its egg, which has a nickname of Baby Yingliang.
After 3 years of research, a group of scientists from China, UK and Canada have found a perfectly fossil of baby dinosaur embryos, the study has been published in the iScience on Dec. 22nd.
This fossil, with a history of 72 to 66 million years, belongs to a theropod dinosaur without teeth, and is the most complete dinosaur embryo in scientific records so far. The preserved state of this dinosaur embryo is quite primitive, without too much interference from fossilization, and clearly shows its state of survival. The total length of the individual from head to tail is estimated to be 27 cm, and it is curled in a 17 cm long egg fossil. The fossil was found in Jiangxi province and later stored in the Yingliang Stone Nature History Museum of Fujian Province.
The research team found that the preservation posture of "Bayby Yingliang" is unique among known dinosaur embryos. Its head is under the body, its feet are on both sides, and its back is curled up along the blunt end of the egg. This posture is similar to that of modern bird embryos, which has never been found in previous dinosaur embryo fossils.
As we all know, birds will produce a series of contraction positions shortly before hatching, that is, bending their bodies and extending their heads under their wings. The research team proposed that the contraction behavior originally thought to be unique to birds may have evolved from theropod dinosaurs tens of millions or hundreds of millions of years ago. The discovery of more embryo fossils will play an extremely important role in further testing this hypothesis. According to experts, this major scientific discovery provides a new and important scientific understanding of the growth, development and reproduction of dinosaurs.
The exquisitely preserved embryo discovered in China was preparing to hatch from its egg just like a chicken.
Embryonic dinosaur fossils are extremely rare — paleontologists have found them at only about half a dozen sites.
‘Exceedingly rare’ find shows dinosaur in a pre-hatching state ‘reminiscent of a late-stage modern bird embryo’.
An unprecedented fossil of a baby dinosaur curled up perfectly inside its egg is shedding more light on the links between dinosaurs and birds.
