Abstract

Well-preserved material of Mariopteris from Friedrichsthal (Saar, German Federal Republic) has convinced the author that Mariopteris nervosa (Brongniart, 1834) Zeiller, 1879 emend. Boersma, 1972 must be looked upon as a withered aspect of M. muricata (Sternberg, 1826) Zeiller, 1879 var. dilatata Lutz, 1938. Since up to the present M. nervosa has been regarded as the type species of the form genus Mariopteris Zeiller, 1879 emend. Boersma, 1972 it is here proposed that M. muricata (Sternberg, 1826) Zeiller, 1879 will be the future type species of the genus.
