The upper Jurassic shark (incooperation with C. Duffin)
Description of a skeleton of the shark Sphenodus macer, the first virtually complete one of the genus, found during the current excavations in the upper Jurassic Nusplingen Lithograpic Limestone, and of teeth of Sphenodus nitidus, common in the same layers. Comparisons between these two and the type species Sphenodus longidens confirm the validity of the three species.

A late Pleistocene herpetofauna of thearcheological site "Kogelstein"
Description and ecological interpretation of a herpetofauna poor in species from the middle paleolithic site Kogelstein near Schmiechen (eastern Baden- Wuerttemberg). The material was collected during an archeological excavation carried out by the Landesdenkmalamt (Land Monument Office).

Stratigraphy of the Grimmelfingen Beds
The new hypothesis on the stratigraphic position of the Grimmelfingen Beds (Brackish Water Molasse, Lower Miocene, MN4a) by Buchner et al. (1996) has been checked by a team under the direction of B. Reichenbacher, Munich. A higher stratigraphic position (Middle Miocen) as supposed by Buchner et al. is not in accordance with on-site findings and biostratigraphic results.

The late Pleistocene fish- and herpetofauna ofthe archeological site "Sesselfelsgrotte"
Within the scope of a research project at the University Erlangen-Nürnberg (under the direction of Prof. Dr. G. Freund) the fish- and herpetofauna found in sediments of the last glacial in the site "Sesselfelsgrotte" in Neuessing in the Altmühl valley (Bavaria) will be described and ecologically interpreted.

Fishes of the Lower Keuper in Baden-Württemberg
Numerous new findings in the last yearsevidence that the Lower Keuper (Middle Triassic, Ladinian) of Baden-Wuerttemberg is richer in fish fossils as known as yet. Thepurpose is to describe them and to analyse their stratigraphicrange and ecology.
