The Bückeberg Formation is a geologic formation and Lagerstätte in Germany. It preserves fossils dating back to the Berriasian of the Cretaceous period. The Bückeberg Formation has previously been considered to constitute the "German Wealden" in reference to its similarity to the Wealden Group in the United Kingdom. More recently it has been considered a group, containing the Isterberg and Deister Formations. The plesiosaur Brancasaurus, an indeterminate ankylosaur referred to Hylaeosaurus, the turtle Dorsetochelys are known from the formation.
