Coptocampylodon? rhaeticus n.sp., a New Problematic Microfossil (“incertae sedis”) from the Rhaetian Dachstein Limestone of the Northern Calcareous Alps (Germany, Austria)

摘要

A new problematic microfossil is described as Coptocampylodon? rhaeticus n.sp. from the Rhaetian Dachstein Limestone of the Northern Calcareous Alps. The new species is composed of a long cylindrical and an irregular rounded body, both showing narrow axial cavity. It is similar to Coptocampylodon? elliotti RADOICIC 1969 from the Cenomanian of Montenegro, but lacks the longitudinal grooves in the cylindrical part. In the Alpine Dachstein Limestone it has been detected at several localities where it occurs as an abundant constituent of biosparitic limestones along with the benthic foraminifera Triasina hantkeni MAJZON, Aulotortus sinuosus WEYNSCHENK, Duostominidae and dasycladales Griphoporella curvata (GüMBEL) and Diplopora adnetensis FLüGEL.
