Messel Pit Fossil Site
Messel Pit is the richest site in the world for
understanding the living environment of the Eocene, between 57 million
and 36 million years ago. In particular, it provides unique information
about the early stages of the evolution of mammals and includes
exceptionally well-preserved mammal fossils, ranging from fully
articulated skeletons to the contents of stomachs of animals of this
period.
