Field guide to the excursions “Fossillagerstätten of the southern German Jurassic” and “Mesozoic ammonoid localities of Switzerland and eastern France”. (original) (raw)

This field guide serves as a comprehensive resource for excursions into the fossil-rich regions of the southern German Jurassic and Mesozoic ammonoid localities in Switzerland and eastern France. It details the ammonite biozones present in the Lower Toarcian section, examines sedimentological conditions such as organic-rich marls and clays, and discusses the significant impact of oxygen availability on fossil preservation. Additionally, the guide includes insights into the geological features of notable quarrying regions, highlighting the importance of water column stratification and sea level fluctuations in the deposition of the Posidonia Shale while featuring eminent fossil sites, particularly the Solnhofen limestone, revered for its exceptional fossil preservation.
