In the quarry "Reckinger Wald" near Brouch in Luxembourg, there occurs, in a lumachel of the "angulata zone" of the Lower Lias, a large quantity of remarkably well-preserved fossils. Both the diversity and the good state of preservation of the gastropods induced the authors to make a survey of this often neglected class of molluscs.
Thirty-four species'have been identified, described and illustrated with photographs. Microschiza clathrata (Deshayes), the most frequently occuring species, lends itself – by virtue of the abundance and variety of specimens – to a statistical survey of variations in its shell. Furthermore, the authors have tried to describe the "angulata zone" paleoecologically and to gain insight into the living-conditions and the sedimentology of the Luxemburg sandstone.
