Dinosaur embryos wiggled around in their eggs just like the embryos of modern birds, scientists have found. The boffins made the discovery after a cache of fossilised dino bones and eggs were dug up in southwest China.
The scientists are hoping to find out more about the Jurassic-era creatures by analysing remnants of complex proteins found in some of the 190-million-year-old fossils.
The researchers studying the oldest dino-embryo fossils ever found have hypothesised that they moved within the egg to exercise muscles and encourage their bones to grow.
DNA’s half-life is about 500 years, though fragments of incomplete degrading DNA remain as the proteins slowly dissolve over hundreds of thousands of years. These remains are 190 million years old. Nevertheless, one of the scientists found it necessary to explain, here, that “resurrecting a dinosaur is out of the question.”
