| Abstract |
Two new genera, Orbiculatisinurostrum and Ryocarhynchus, with type species O. laeve (GURICH, G., 1903) and R. tumidus (KAYSER, E., 1872), are described from the late Frasnian. The former genus is encountered in the lower part of the Palmatolepis triangularis Zone near Cracow (Poland). The latter one includes two species, and is the result of restricting the meaning of the genus Caryorhynchus CRICKMAY, C.H., 1952; it is found in the Palmatolepis gigas Zone — essentially Upper and Uppermost — of the southern border of the Dinant Basin (Belgium and France), the Aachen region (Germany), the Tafilalt (Morocco), and near Cracow. |
