A revision of Devonian trilobites from Belgium - Part 2. The genera Gerastos and Cornuproetus

Belgian Devonian trilobites have long been known, although they remain comparatively poorly documented. A revision of the obsolete nomenclature seems long overdue, and added to that, critical evaluations of listings of trilobite taxa by MAILLIEUX over sixty years ago are called for. The present note is the second part of a revision of Devonian trilobites from Belgium, and comprises data from locality ARD004 at Resteigne and locality ARD005 at Couvin (Ardennes, Belgium), which yielded the new material. It briefly discusses correlations of Middle Devonian (Eifelian) successions of the Ardennes and Eifel (Germany), and describes two taxa (Gerastos dhondti n. sp. and Cornuproetus cornutus) from Couvin and one taxon (Gerastos prox) from Resteigne
