Süntel Formation
The Süntel Formation, previously known as the Kimmeridge Formation (German: “Mittlerer Kimmeridge”; Middle Kimmeridge),[1] is a geological formation in Germany. It is Late Jurassic in age, spanning the early to late Kimmeridgian stage. It predominantly consists of limestone deposited in shallow marine carbonate ramp conditions.[2]

Description
Map of the Lower Saxon Hills with Süntel center-right
The formation is part of the Lower Saxony Basin that borders the Süntel massif of the Lower Saxon Hills, part of the larger Harz Mountains. The formation is described as alternations of glauconitic marl, limestone and sandstone.[3]
Paleontological significance
The formation is known for its fossils, with the Langenberg Quarry having provided fossils of numerous vertebrates.
