The genus Temnocidaris (Echinoidea, Cidaroida) in the Upper Cretaceous and Lower Tertiary of the Maastricht Area (Belgium and The Netherlands)

In the chalk-deposits of Limburg (Belgium and the Netherlands) the genus Temnocidaris is represented by two species, T. baylei and T. danica . The former is confined to the Maastrichtian, the latter to the Danian. Temnocidaris is biostratigraphically useful in the Limburg chalk, even when only small coronal fragments or isolated plates are available.
