Two dinosaur eggs discovered in China filled with crystals
Paleontologists in China have discovered two eggs, belonging to a previously unknown type of dinosaur, filled with crystals (crystals) in the Qianshan Basin in eastern Anhui Province.
The two eggs were classified as Shixingoolithus qianshanensis, making them a newly described, previously unknown.
According to the researchers, the two eggs are "semi-spherical" about the size of a cannonball, with a length of 105 to 137 mm, and a width of 99 to 134 mm. One of the eggs was found partially broken and its inner surface was "covered with a crystalline layer of calcite".
The study authors explained that calcite is a carbonate mineral commonly found in the eggs of birds and dinosaurs. Calcite crystals form when calcium carbonate, which is also used to strengthen bones, teeth and nails, separates from the eggshell structure and accumulates on its inner surface in slowly growing crystals.
A previous study had indicated that a close species of dinosaurs lived on the surface of the earth during the last part of the Triassic period (251.9 million to 201.3 million years ago) to the late Cretaceous period (145 million to 66 million years ago).
