Middle Miocene (Badenian) gastropods from Korytnica, Poland. Part 4, Turridae

100%

Bałuk W.

Acta Geologica Polonica

2003

tom Vol. 53, nr 1

29-78

This report is the fourth part of the monograph of the surprisingly rich assemblage of gastropods occuring in the socalled Pleurotoma Clays of Middle Miocene (Badenian) age, exposed in the environs of Korytnica in the Holy Cross Mountains, Central Poland. It contains characteristics of 101 prosobranch species of one family, the Turridae. Within this assemblage, five species are new for the science (including one, formerly reported from Korytnica, but determined erroneously); of the recognized species as many as 72 have not hitherto been reported from Korytnica, and 66 from the Miocene of Poland. As the new species established are: Clavatula kowalewski sp.nov., Perrona (Perrona) czarnocki sp.nov., Turricula (Surcula) korytnicensis sp.nov., Cythara (Mangelia) cibori sp.nov., and Bela sanctacrucensis sp.nov.

Paleobiogeography of turrid gastropods in the Pliocene of Catalonia

Gili C. , Martinell J.

Acta Palaeontologica Polonica

1993

tom 38

nr 3-4

The distribution of the Turridae in the Pliocene of Catalonia (NE Spain) is heterogeneous. It appears to be determined to a greater extent by the particular autoecological traits of each species than by more general environmental factors. The area formed by the Pla de Barcelona and the Baix Llobregat may be regarded as a bio-geographical unit due to turrid species, which do not occur in other basins. The turrid distribution in the Alt Empordà basin manifests a high degree of environmental diversity among the different outcrops of the area, thus confirming the earlier provided taphonomic and biogeographic data. Species of the Turridae from Poble de Siurana (Alt Empordà) are also present in different parts of the Pla de Barcelona and Baix Llobregat areas. This indicates the existence of similar ecological enclaves in both basins, within a quite different general context.
