The Obernkirchen Sandstein or Obernkirchen Sandstone is a geological unit in Lower Saxony, Germany whose strata date back to the Early Cretaceous. The remains of the dinosaur Stenopelix and numerous dinosaur tracks are known from the unit.[1][2] The unit is a thin interval within the Bückeberg Formation As its name would suggest the lithology primarily consists of sandstone with thin intercalations of coal. This was deposited in a sandy barrier to lagoonal complex setting. The unit has historically been extensively quarried for its high quality building stone, which has been used as far away as Jakarta.
