It’s no secret that dinosaurs tended to live in the same habitats as birds. In fact, there is a fossil from China that shows a dinosaur embryo tucked inside an egg 66 million years ago. This embryo was discovered by a Chinese researcher. It was called Baby Yingliang, and it had its head tucked under its body, feet on either side, and back curled around the blunt end of the egg. In fact, it resembled a modern bird in its posture.
This study is the first to find dinosaur embryos tucked into eggs in the same manner as modern bird embryos. The central nervous system controls tucking and is crucial to successful hatching. The researchers examined both the egg and embryo to identify which behavior is related to the development of pre-hatching behaviour in birds. Before Baby Yingliang, pre-hatching behaviour was only known to occur in birds.
Previously, it was thought that only birds were capable of tucking themselves in. However, new research indicates that dinosaurs may have done the same. Researchers from China, Canada, and the United Kingdom have discovered that tucking was a common behavior in birds. This behaviour is similar to that of birds. The study’s results are promising, and these findings can be used in future studies of fossilized embryos.
The tucking posture is unique to birds. The tucking posture is an adaptation to the tucked posture in birds. This behavior is thought to have evolved independently from birds, but it is not yet clear if this was the case. In the meantime, the study also suggests that tucking behavior evolved independently from modern birds.
This behaviour is likely derived from non-avian dinosaurs. Interestingly, Baby Yingliang, a 66 million-year-old dinosaur embryo, resembles the late-stage bird embryo. Its head was tucked below its body and its feet were on either side. The two of them are believed to be very similar.
In addition to being a highly efficient way to lay eggs, dinosaurs may have also been tucking in their eggs. This ancient method was previously thought to be unique to birds, but this recent discovery shows that dinosaurs were also adept at tucking in their eggs. In fact, the tucking of embryos in the eggshells of birds had a beneficial effect on the development of modern bird hatchlings, resulting in the emergence of the modern bird.
Another way that dinosaurs tucked themselves in is through the way they lay their eggs. Many of the embryos they laid were shaped like birds, but some of them were not tucked in at all. Other oviraptorosaur embryos were damaged during preparation, and therefore are incomplete. This new fossil, if preserved correctly, could act as a “Rosetta Stone” for the others that may be hiding in the rocks of the fossils.
