| Abstract |
A well-preserved cidarid echinoid is recorded from Interval 5 or 6 of the Vijlen Member (Gulpen Formation, Maastrichtian), as exposed in and along the banks of the River Maas at Eijsden. In contrast to occurrences in the Zeven Wegen (Gulpen Formation, Campanian) and Nekum and Meerssen members (Maastricht Formation, Maastrichtian) in the area, the Vijlen Member has so far yielded but limited cidarid material. In addition, when specimens are found preservation is generally poor, the material consisting of isolated primary spines and test plates and/or portions of test at best. The present specimen, which is here questionably referred to Temnocidaris (Stereocidaris) arnaudi (LAMBERT, 1909), is of note in being complete, albeit slightly deformed, and in retaining the lantern, some primary, secondary and scrobicular spines and a few peristomial plates. |
