Dentaliids (Mollusca, Scaphopoda) from the type Maastrichtian, the Netherlands and Belgium

Scaphopods remain poorly known from the type area of the Maastrichtian Stage in northeast Belgium and the southeast Netherlands. At least three species appear to be represented, but incomplete preservation (i.e., lack of shell material) hampers a detailed systematic treatment of most specimens. In museum collections, the name Dentalium nysti Binkhorst van den Binkhorst, 1861 (= D. binkhorsti Pilsbry & Sharp, 1898; non D. nysti d’Orbigny, 1852) is often used rather indiscriminately for both genuine scaphopods and internal moulds of serpulid worm tubes. Here, we describe and illustrate Antalis? binkhorsti, Fissidentalium? sp. 1 and Dentaliidae sp. indet., all of Maastrichtian age, as well as a late Campanian form, Fissidentalium? sp. 2.
