| Cretaceous Strata in Nanxiong Basin of Guangdong and the Evolution from the Dinosaur Egg to the Bird Egg |
| A complete Cretaceous stratigraphic section in Nanxiong Basin was surveyed, and lots of dinosaur eggs including a new family, two genera and six species were found from sixty-six layers in this section. A unified stratigraphic nomenclature for the strata of Nanxiong Basin and Danxia Basin is proposed on the basis of stratigraphic correlation. The findings of the Pinnatoolithidae reveal the evolution from the dinosaur egg to the bird egg, which is characterized by the variation of the prismatic layer of egg shell from the layer structure to the pinnate structure. Compared with eggs of the living bird, the prismatic layer of the dinosaur egg should correspond to the layer of squamate aggregates of the bird, and the egg with the pinnate structure is the transition from the dinosaur egg to the bird egg. |
