Qiupa Formation

The Qiupa Formation is a

Henan Province, central China. It is rich in dinosaur eggs and bones, such as those of carnivorous and herbivorous dinosaurs. The Qiupa Formation is considered to be Late Maastrichtian in age, about 72 million and 66 million years ago.[1][2][3]

Geology

The sedimentation is characterized for the presence of calcareous

river deltas.[2][3]

Fossil content

The Qiupa Formation has yielded numerous dinosaur fossils, particularly eggs. The remains of various theropods such as

turtles and a possible avian bone are reported.[4][2]
