No. My only visit was to the Reis crater that was to do with Asteroid impacts but I studied a course in my undergraduate degree on Past Ecosystems which covered two Periods. One was the The Jurassic Solnhofen Limestone (laid down I believe at the same time as the clays that hold the North Sea Oil were laid down, and the other was the Holzmaden Shale). I recall that the Holzmaden Shale and the Solnhofen Limestone and the Reis crater were all located near the Schwabische Alb (German for Alp). The asteroid impact was thought to be part of a binary asteroid, and there's another smaller crater to the South West of Nordlinger called Steinheim. Apparently to the East you can find green glass called tektites which is melt from the impact that was ejected from the impact crater. It is very interesting. Astronauts from the Apollo mission went to the Ries crater as part of their preparation for the moon landings.Some background: Hoffenheim is small - but it is part of the Rhine-Neckar Metropolitan Region

Have you visited the Grube Messel https://en.wikipedia.org/wiki/Messel_pit - as you seem to be into that topic?
