Here, examples of these two taxa are described and illustrated. <i>Radulichnus</i> traces are left on a lithified substrate by the radula of certain gastropod and/or polyplacophoran (chitonid) molluscs, while <i>Renichnus</i> are etched traces of shells of vermetid gastropods. Vermetids from the Maastricht Formation are briefly discussed; an example of <i>Vermetus clathratus</i> BINKHORST, 1861 is illustrated. In addition, the ichnofossil <i>Centrichnus eccentricus</i> BROMLEY & MARTINELL, 1991, the byssal etching trace of anomiid bivalves which bears a superficial resemblance to <i>Renichnus</i>, is also documented.","AbstractOtherLang":"Le faciès tuffeau (biocalcarénites) de la Formation de Maastricht (Maastrichtien terminal) dans sa région type (SE des Pays-Bas, NE de la Belgique) a livré de nombreux taxa d'ichnofossiles.
