Phytoplankton evidence for the timing and correlation of palaeoceanographical changes during the early Toarcian oceanic anoxic event (Early Jurassic)

The causes and duration of the early Toarcian anoxic event are controversial. Integration of data from calcareous and organic phytoplankton provides a biochronological framework that allows precise

Overgrowth on ammonite conchs: environmental implications for the Lower Toarcian Posidonia Shale

Ammonites of the south–west German Posidonia Shale (Early Toarcian) are occasionally overgrown by bivalves, brachiopods or serpulids. Attachment to both sides of the conchs in some specimens suggests

Evidence for local carbon‐cycle perturbations superimposed on the Toarcian carbon isotope excursion

Connecting new carbon and oxygen isotope data with documentary lipid biomarkers shows that the global carbon cycle during the Toarcian OAE was disturbed by enhanced green sulfur bacteria (GSB) metabolisms and early diagenesis at local scales.

The Lower Jurassic Posidonia Shale in the Swabian Alb Geopark – Geoeducation in an Industrial Environment

The Lower Jurassic Posidonia Shale of Southern Germany is famous for its excellently preserved fossils. First of all, the large and spectacular ichthyosaurs, pterosaurs and crocodiles impress. Fish,
