Although these fish faunas have been intensively studied for a long time, the whole region is still attractive for palaeoichthyological exploration today. The Hermanowa locality is located in southeastern Poland, about 12 km south of the center of Rzeszow Editorial handling: D. Marty. (Fig. 1). Kotlarczyk et al.

The specimens were collected from a single outcrop (Fig. 2; GPS lat 49.934266; long 22.019500), located in the Hermanowa village. The presence of the index species 2 Material and locality Trachinus minutus (distributed in all parts of the profile) allows the assignment of the locality to the Trachinus event The material is housed at the University of Rzeszow (UR/ of the IPM2 zone (for the palaeoecologic interpretation of KBS´), Institute of Systematics and Evolution of Animals, this event see Kotlarczyk et al. 2006).

Remarks The specimen was discovered in the lower part Remarks Clupeids from the Polish Carpathians were of the section. The occurrence of the species was recorded traditionally classified as Clupea sardinites (Jerzman´ska from the Early Oligocene of Belgium (Leriche 1910; Bor 1968; Szymczyk 1978), but Daniltshenko (1980) and later 1980), Paris Basin (Leriche 1910), Hungary (Weiler 1938), also Grande (1985) suggested transferring this species to France (Pharisat 1991, 1998; Pharisat and Micklich 1998), the genus Sardinella.
