The Contents of the Eocene Trap
For many years, the Messel maar lake acted as a collection and sedimentation pond for mud particles, carcasses, and plant remains. The maar lake sediments contain a mixture of plant and animal remains from the former lake itself and from its surroundings, representing a small part of a large primeval forest. For nearly a million years, the lake supported creatures
that were later fossilised. The disintegration of the animals before they were embedded varied, so their remains occur as both complete skeletons and isolated bones. Strong algal growth and poor aeration ensured an extremely low oxygen content in the water and therefore suitable conditions for anaerobic bacteria. This was responsible for the incomplete decay of the organic substances that form kerogen. Because the water was more or less stably stratified, the lake type is described as meromictic.
