A note on Salenia Gr. nutrix Peron and Gauthier, 1881 (Echinoidea) from the Maastrichtian type area (southeastern Netherlands, northeastern Belgium)

A single specimen of a saleniid echinoid recently collected from the Late M aastrichtian of the type area of the Maastrichtian Stage is notable in bein g closely related to Salenia nutrix Peron and Gauthier, 1881. Representativ es of the "nutrix group" have previously been recorded from the Late Cretac eous of the Mediterranean and north Africa. The occurrence in the type Maas trichtian of a representative of this group thus furnishes additional evide nce of Tethyan incursions in the area during the Late Maastrichtian.
