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.

Outstanding Universal Value
Brief synthesis
Messel Pit provides the single best fossil site which contributes to the understanding of evolution and past environments during the Palaeogene, a period which saw the emergence of the first modern mammals. The property includes a detailed geological record of middle Eocene age, dating from 47-48 million years ago. It provides unique information about the early stages of the evolution of mammals and is exceptional in the quality of preservation, quantity and diversity of fossils of over 1000 species of plants and animals, ranging from fully articulated skeletons to feathers, skin, hair and stomach contents. Located in the German Land of Hesse, this area of just 42 ha conserves a rich fossiliferous bed of oil shale some 190 m thick. Discovered through mining activities, the area has now been preserved and has been the subject of important paleontological research, which has greatly contributed to our knowledge of evolutionary history. Significant scientific discoveries include studies of the evolution of echolocation in exceptionally well-preserved fossil bats and vital new data on the evolution of primates, birds and insects.
Criterion (vii): Messel Pit Fossil Site is considered to be the single best site which contributes to the understanding of the Eocene, when mammals became firmly established in all principal land ecosystems. The state of preservation of its fossils is exceptional and allows for high-quality scientific work.
Integrity
As the Messel Pit is the former site of an oil shale mine, the land surface has been significantly disturbed. Paradoxically, if there had been no mine, the scientific values of the property would have never been discovered. Once mining was discontinued in the late 1960’s, the site was opened to private prospection and even proposed as a refuse dump in 1971, a threat that led to increased scientific prospection and public concern. This culminated in the purchase of the pit by the government and its full protection as a cultural monument. The extraordinary state of conservation of the property’s fossils, which allows for the reconstruction of the morphology of the preserved fauna and flora as well as that of their environment, and the serious commitment by government for its long-term maintenance as a site of scientific importance, means that the conditions of integrity for the property are fully met. Although much material has been taken from the site - approximately 20 million tonnes of rock in a century of mining activities - the volume of fossil-bearing oil shale sediments is still massive and far from depleted.
Protection and management requirements
The Land of Hesse is the legal owner of the Messel Fossil Pit. The oil shale in the pit is a historical mineral resource, making it part of the cultural heritage as defined in the Hessian Heritage Protection Act. Operations in the mine are governed by the Federal Mining Act. The property is jointly managed through an agreement between the government, the Senckenberg Society for Nature Research and the Messel Pit World Heritage Non-Profit Limited, an NGO founded in 2003, which has as its principal responsibility the presentation of the site to visitors. Shareholders of this NGO are the Land of Hesse, the Senckenberg Society for Nature Research and the municipality of Messel. The Messel Pit Fossil Site is administrated separately from the Federal State budget.
Under German law, the Senckenberg Society for Nature Research is the operator of the mine, which has an agreement with the Land of Hesse for the protection and preservation of the Messel Pit. The operator is responsible for the main operating plan of the mine, which includes water drainage, slope reinforcement, management of encroaching vegetation, protection against trespassers and management of the former North-East Dump, as well as for sustaining scientific research. The property is surrounded by a perimeter fence and controls on excavation and disturbance to the oil shale are in place. Various development and landscape plans for the property have been produced, as well as an overall Management Plan. A 22.5 ha buffer zone surrounding the property was defined in order to strengthen the integrity of the property and support its effective protection and management. A viewing platform overlooking the pit, a visitor information centre and a wide range of communication activities concerning the property are in place.
Long Description
The Messel Pit has provided a wealth of fossils that have greatly increased understanding of the Eocene Age. It is a small site approximately 1,000 m long (north to south) and 700 m wide (east to west).
The Eocene ('dawn of new times') epoch (57-36 million years ago) was a remarkable period in the evolution of life on Earth. This was the time when mammals became firmly established in all the principal land ecosystems. They also reinvaded the seas (e.g. whales) and took to the air (e.g. bats). During this period of geological time, North America, Europe and Asia were in continuous land contact and the partial explanation of current distribution patterns is provided by the Eocene fossil record.
The Messel Pit provides the single best site which contributes to the understanding of the middle part of this period. Messel is also exceptional in the quality of preservation, quantity and diversity of fossils. Messel offers fully articulated skeletons and the outline of the entire body as well as feathers, hairs and stomach contents.
The sediments of the Messel formation lie on deposits of 270-290 million-year-old Red Sandstone and crystalline magmatic primary rock outcrops.
During the Eocene epoch, subsidence along faults in the Earth's crust led to the formation of a lake basin. The gradual subsidence of old sediments resulted in the formation of new sediments above them, and over time immense deposits accumulated. The oil-shale bed at Messel originally extended to a depth of 190 m. The subsidence of the deposits preserved them from erosion. Outcrops of older seams from the Eocene succession are found on the slopes of the pit. The location of the Eocene Lake Messel lay south of its present position. This accounts for the site appearing to have had a tropical to subtropical climate.
The fossils found here are providing a unique insight into an early stage of mammal, evolution when many of the basic steps in diversification were being achieved. But mammals were not the only component of the fauna - birds, reptiles, fish, insects and plant remains all contribute to an extraordinary fossil assemblage.
In terms of fossil localities which provide a window into the Eocene Age, Messel is the best and most productive example discovered to date. In contrast to other fossil sites that are marine, Messel can be considered as the single best 'classic' locality snapshot of life as it was in the Eocene. It has been identified as one of the four most significant fossil sites in the world by several senior palaeontologists.
