The Hekou Formation is a Cretaceous geologic formation in China. Pterosaur fossils have been recovered from the formation. It is a unit of the Guifeng Group and dates to the Late Cretaceous (Coniacian-early Campanian).[1] Dinosaur fossils from the formation include a nearly perfect oviraptorid embryo nicknamed Baby Yingliang, an unnamed large hadrosaurid, and hadrosauroid eggs with embryos.[2][3][4] Mammal fossils include Erythrobaatar and Yubaatar qianzhouensis.[5][6] The polyglyphanodontian lizard Yechilacerta has also been described from the formation.[7]
