Palaeontology: Pterosaur embryo from the Early Cretaceous
Xiaolin Wang & Zhonghe Zhou
Abstract
An impressive fossil discovered in China confirms that pterosaurs were egg-layers.
Abstract
Dinosaur embryos have been discovered all over the world1, 2, but so far no pterosaur embryos have been reported. Here we describe a Chinese fossil from the Early Cretaceous period containing an embryo that is unambiguously a pterosaur. The embryonic skeleton, which is exquisitely preserved in its egg, is associated with eggshell fragments, wing membranes and skin imprints. This discovery confirms that pterosaurs were egg-layers and sheds new light on our understanding of pterosaur development.
