High resolution biostratigraphy in the Upper Jurassic of southern Germany with the help of ammonite faunal successions.

The small ammonite Amoeboceras bauhini is very important for the correlation between England and southern Germany. Here is a specimen from the Pletteberg quarry near Balingen (Swabian Alb).

Phylogeny of the ammonite family Strigoceratidae (Middle/Late Jurassic).

The ammonite genus Phlycticeras is characterized by a spiral strigation. Phlycticeras has an almost cosmopolitic distribution and is thus a good tool for long-distance correlations.

Excavations in the famous fossil lagerstaette of Nusplingen (Upper Jurassic).

Excavation in the lithographic limestones of the Nusplingen quarry. Since 1993 a team of the Natural History Museum of Stuttgart exploits one of the most important fossil sites of SW Germany. Up to the present, more than 300 taxa were recorded from these lithographic limestones, many of them are not known from elsewhere.

Investigation of the fossil lagerstaette Randeck Maar (S Germany, Lower Miocene).

The Randeck Maar provides very important data on the vegetation, fauna and climate during the Early Miocene (17 my ago). The laminated deposits of a former crater lake yield a rich fossil flora and fauna.

Decription and revision of decapod crustaceans of the Jurassic.

Reconstruction of the lobster Uncina posidoniae from the Posidonia Shale of Holzmaden. This decapod reached a length of about half a meter. It is one of the largest fossil decapods ever found. The genus Uncina occurs not only in southern Germany, but also in the Alps, in Canada, and even in Japan.
