Belemnitellid coleoids abound at some levels within the Gulpen and Maastricht formations in the study area, and ‘belemnite graveyards’ have long been known from the Bovenste Bos (Epen) and Slenaken-Beutenaken areas in southern Limburg, the Netherlands. Recent studies have demonstrated the presence of at least three species of the genus Belemnitella d’Orbigny, 1840, and five of Belemnella Nowak, 1913, and its subgenera Belemnella, Pachybelemnella Schulz, 1979, and Neobelemnella Naidin, 1975. Representatives of Belemnitella junior Nowak, 1913, and Belemnella (Neobelemnella) gr. kazimiroviensis (Skołozdrówna, 1932) are the only coleoids to reach the Cretaceous-Paleogene (K/Pg) boundary, and members of the latter group may even have persisted into the earliest... |

A synthesis of the stratigraphy of the Maastrichtian Stage in its extended type area, that is, southern Limburg (the Netherlands), and adjacent Belgian and German territories, is presented with a brief historical overview. Quarrying activities at the large quarry complex of ENCI-HeidelbergCement Group will officially come to an end on July 1, 2018. However, the stratotype section below the Lichtenberg farmstead and directly behind the main office building at the Lage Kanaaldijk (Maastricht), will be preserved, as will various faces within the quarry complex. Strata of Maastrichtian age include the Vijlen, Lixhe 1-3 and Lanaye members of the Gulpen Formation, as well as the Valkenburg, Gronsveld, Schiepersberg, Emael, Nekum and Meerssen members of the... |

Ray-finned fishes are a diverse, but understudied, component of the Maastrichtian marine fauna of the southeast Netherlands (Limburg) and northeast Belgium (Liège-Limburg). The most extensive reviews of fishes from these uppermost Cretaceous deposits were made in the early and mid-Twentieth Century, but little research on this important assemblage has been executed since. The present paper provides figures and brief descriptions of fishes from the Maastrichtian type area as an aid for field identification of fossil discoveries. A simple key to common Maastrichtian fish teeth from this area is also included. All convincing records of ray-finned fishes from the Maastrichtian of the Netherlands and Belgium, inclusive of the Mons Basin, are teleosts, and... |
