Abstract
Two species of crustacean microcoprolites belonging to the ichnogenus Palaxius - Palaxius caucaensis Blau, Moreno & Senff and Palaxius isp. - are described from Cretaceous (Upper Cenomanian-Turonian) deposits of the Maghra El Hadida Formation in northeast Egypt. Palaxius caucaensis was so far known only from the type locality (Campanian-Maastrichtian) of Colombia. The Turonian Maghra El Hadida Formation in Egypt is the second locality from which this ichnospecies is reported. Thus, the stratigraphic range of P. caucaensis may be extended from the Turonian to Maastrichtian, although it is not known from the Coniacian-Santonian time interval. Palaxius isp. is poorly preserved. The determination of this Palaxius at species level is not possible, because de-dolomitation has wiped out the outlines of the internal canals. Therefore, the number and arrangement of the longitudinal canals around the symmetry plane are not recognizable in detail. Palaxius isp. is, however, extremely abundant in the investigated thin sections in uppermost Cenomanian limestones. The two described ichnospecies do not occur together.
