Foraminifera from the Triassíc Muschelkalk facies are rare and their diversity is low. Tite recorded species are mainly Lagenidae characterized by hyaline calcite walls. Other foraminifera (Involutinidae, Duostiminídae), well knowri in the Trias of the Alpine facies province (Tethys), seemed not to occur in the German facies province possibly because of anomalous conditions of the bottom waters. However, recent work has shown titat foraminifera of the Alpine facies province occur also, however rarely and not always well preserved, in the Muschelkalk of Sardinia, Germany, Luxemburg and South Tunisia. Their infrequency and poor preservation are explained as the result of diagenetic changes in the course of fossilization combined with a very low rate of sedimentation, rather than of adverse living conditions.
