Santonian macrofauna and nannofossils from northeast Belgium

From a limited number of mine shafts in the Belgian province of Limburg (Houthalen and Zolder/Voort areas), a small fauna comprising ammonites, belemnites and inoceramid bivalves is described. A nannofossil analysis of samples taken from the ammonites is added. This assemblage is of (late) middle to late Santonian age, and thus roughly corresponds to the 'Craie de Lonzee' (province of Namur, Belgium) and the Aachen Formation of the Aachen-Vaals area (SE Netherlands and Germany).
