Tenuipteria geulemensis (Mollusca: Bivalvia), an inoceramid species from the upper Maastrichtian of the Sint Pietersberg area, The Netherlands

The inoceramid species Tenuipteria geulemensis (F. Vogel, 1895) is recorded for the first time from the Upper Maastrichtian ( Belemnella junior and B. casimirovensis Zones) in the Maastrichtian type area (Sint Pietersberg, Maastricht, The Netherlands). It can be used as an index fossil for the Upper Maastrichtian in northern and eastern Europe, and is very similar to the North American Maastrichtian species T. argentea (Conrad).
