Gram Formation (Denmark)

The Gram Formation is a geological formation in Gram, Denmark. It preserves fossils dating from the Miocene period. The formation consists 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.

## Fossil content

Many fossils of new species have been discovered in the formation, including those of the beaked-whale Dagonodum mojnum[1] and the mollusk species Pseudocochlespira gramensis,[2] as well as specimens of better-known species such as Carcharodon megalodon.[3]
