The Dabeigou Formation is a palaeontological formation located in Hebei, China.[1] It dates from the mid Valanginian to Hauterivian age of the Cretaceous period, approximately 135 to 130 Ma.[2]

Fossil content[]

Fossils include the confuciusornithiform bird Eoconfuciusornis.[3] As of 2016[verification needed] this is the oldest bird with a toothless beak known, but it belongs to a very ancestral avian lineage not closely related to living birds.
