Der baubini-Faunenhorizont und seine Bedeutung fur die Korrelation zwischen tethyalem und subborealem Oberjura / Фаунистический горизонт Баубини и его значение для корреляции между тетиальной и суббореальной верхней юрой

The ammonite fauna of the so-called ,bauhini horizon" is described in detail. The material comes from the Upper Danube valley and from the Lochen area (SW Germany). The bauhini horizon marks the youngest horizon of the Hauffianum Subzone (Late Oxfordian) of the Te-thyan chronozonation. The comparison of amoeboceratids permits a correlation of this horizon with the base of the Subboreal Kimmeridgian (Baylei Zone, densicostata horizon). Hence the bauhini horizon is demonstrated to be one of the most important levels for correlations. Three new ammonite species are described from the bauhini horizon: Metahaploceras muehl-heimense n. sp., Physodoceras wulfbachense n. sp., and Pictonia praeperisphinctoides n. sp. A brief survey is given of the ammonite faunal horizons below and above the bauhini horizon.
