An international team of researchers led by the Museum für Naturkunde Berlin has described Germany's first fossil freshwater shrimp species in the journal Scientific Reports. Most shrimps love marine habitats, but this 48-million-year-old fossilized shrimp from the Eocene comes from the UNESCO World Heritage Site Grube Messel, a former freshwater lake. Since even rare organ structures have been preserved, the shrimp is another piece of the puzzle in the reconstruction of this unique ecosystem.
