The Qiupa Formation ({{zh|s=秋扒组|p=Qiūpázǔ}}) is a Late Cretaceous Maastrichtian geologic formation in 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.{{cite book|author=Bureau of Geology and Mineral Resources of Henan Province|date=1989|title=Regional Geology of Henan Province|publisher=Geological Publishing House|location=Beijing|pages=1−772}}{{cite journal |last1=Lü |first1=J.
