Gram Formation
The Gram Formation is a geologic formation in Gram, Denmark. It preserves fossils dating from the Miocene period. The formation is made of three layers: the glauconite-rich, the Gram Clay, and the Gram sand. The sediments in the formation were deposited in an open marine depositional environment known as the Gram Sea.Many fossils of new species have been discovered in the formation, including those of the beaked-whale Dagonodum mojnum and the mollusk species Pseudocochlespira gramensis, as well specimens of more well-known species such as Carcharodon megalodon.
