Santonian - Campanian (Upper Cretaceous) inoceramids from the Houthalen mineshaft, NE Belgium
Published on Jan 1, 2005
The Santonian and Campanian inoceramids from the Houthalen mineshaft (Limburg, NE Belgium) are described. Four successive faunas were distinguished: the Sphenoceramus pachti fauna, dated for the Middle Santonian, the Sphenoceramus patootensiformis fauna, of the upper Upper Santonian - lower Lower Campanian, the Cordiceramus paraheberti fauna, possibly of the upper Lower Campanian, and the Inoceramus tenuilineatus fauna, characteristic for the middle Upper Campanian. The appearance of the latter fauna marks one of the main turnover events in the evolution of the Campanian inoceramids.
