STUDY OF THE JURASSIC AMMONITES
Professor Friedrich August Quenstedt
The Swabian Alb region is not only home to many of the best-researched ammonite sites in the world, it is also where the studies of the ammonite fauna of the Jurassic period began.
The three-part book by Tübingen professor Friedrich
August Quenstedt from the years 1883 to 1888 is regarded one of the most fundamental and famous works. Quenstedt was also the one who developed the tripartite division of the Jurassic strata into the Black, Brown and White Jurassic, which is still valid today, and who correlated the different rock layers on the basis of their typical ammonites.
