Abstract

A suite of Early Mesozoic (Late Triassic, Norian to Early Jurassic) calcareous
beds was studied from the Hochfelln Massif in the Northern Calcareous
Alps (Bavaria, South Germany). The main part of the Hochfelln Mountain is
built up by the Hauptdolomit Group consisting of thick peritidal deposits
and overlain by basin deposits of the Rhaetian Kössen Formation and
Rhaetian reefoidal limestone with corals. Unlike many other sections in
the Tethys realm, coral growth seems to continue into the Jurassic or starts
again relatively early within the Early Jurassic. Silicified corals and other
marine invertebrates are present in the calcareous, micritic Hochfelln
Beds. A reexamination of previously collected ammonite material indicates
the presence of Coroniceras sp. which suggests an Early Sinemurian
age for the Hochfelln Beds (= Hochfellnkalk). Abundant sponge spicules
(spiculites) suggest that sponges were the source for the silicification. The
historical gastropod collection (Bayerische Staatssammlung für Paläontologie
(BSP), Munich) from the Hochfelln Mountain was reexamined and
new material was collected. The Hochfelln gastropod fauna yields a total
of 28 species. It represents one of the richest Early Jurassic gastropod
faunas of Germany and the Northern Calcareous Alps. The generic assignments
of several species were changed and twelve species were newly reported
some of which are undescribed. The relatively diverse Early Sinemurian
gastropod fauna together with the coral growth on top of the
Hochfelln Mountain indicate rapid recovery from the end-Triassic biotic
crisis.
