Bückeberg Formation

The Bückeberg Formation is a geologic formation and Lagerstätte^[1] in Germany. It preserves fossils dating back to the Berriasian of the Cretaceous period.^[2] 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.^[3] More recently it has been considered a group, containing the Isterberg and Deister Formations. The plesiosaur Brancasaurus,^[4] an indeterminate ankylosaur referred to Hylaeosaurus,^[5] the turtle Dorsetochelys are known from the formation.
