| Abstract |
The tuffaceous chalk facies (biocalcarenites) of the Maastricht Formation (Late Maastrichtian) in its type area (SE Netherlands, NE Belgium) has yielded numerous ichnofossil taxa; however, the genera Radulichnus and Renichnus were not yet recorded. Here, examples of these two taxa are described and illustrated. Radulichnus traces are left on a lithified substrate by the radula of certain gastropod and/or polyplacophoran (chitonid) molluscs, while Renichnus are etched traces of shells of vermetid gastropods. Vermetids from the Maastricht Formation are briefly discussed; an example of Vermetus clathratus BINKHORST, 1861 is illustrated. In addition, the ichnofossil Centrichnus eccentricus BROMLEY & MARTINELL, 1991, the byssal etching trace of anomiid bivalves which bears a superficial resemblance to Renichnus, is also documented. |
