Eckfeld Maar: Window into an Eocene Terrestrial Habitat in Central Europe

: To mark the occasion of the 175th anniversary of the Rheinische Naturforschende Gesellschaft in 2009 and of the centennial of the Mainz Natural History Museum in 2010, we present a short account of our present knowledge of the Eckfeld Maar after 20 years of continuous research. This paper does not attempt to include all of the detailed results on the geology of the Eckfeld site or its biota. To date, nearly 250 papers and books have been published since the start of our project An up-to-date list of these publications can be found at http://www.eckfeldermaar.de.
