The
so called Messel Pit (also called Messel oil shales) is
a world famous fossil Lagerstätte of Eocene age (about
47 million years ago) some 20 miles from Frankfurt, Germany.
The area’s oil shales were actively mined in the
19th century. The fossils from Messel are extraordinary
due to magnificent soft tissue preservation. Stomach contents
and color have also been found preserved. The fossils come
from water laden sediment, and require special processes
to remove and transport, including embedding them in resin.
Messel is also an exceptional fossil site due to the diversity
of organisms found, including a wide variety of mammals
(e.g., bats, kopidodons and other rodents, leptictidiums,
creodonts, anteaters, tapirs, hedgehogs, and many more)
as well as marsupials and several early primates. Many
bird fossils have been recovered, including early or proto
ostrich, hunters resembling hawks and owls, and other birds
related to hummingbirds and sandpipers. Reptiles are well
represents, including crocodiles, alligators, snakes, turtles
and lizards. The diverse fauana also includes fish and
insects.
