Notes on the Cretaceous invertebrate faunas of Portugal I:a new species ofAnadromus (Mollusca, Gastropoda) from the Campanian-Maastrichtian of Taveiro (Coimbra, West central Portugal)

Abstract

Key-words: Anadromus; Gastropoda; Campanian-Maastrichtian; Cretaceous; Taveiro; Portugal. Anew species of terrestrial gastropod - Anadronws pellai sp. nov. (Fam. Anadromidae) - is described from a set of composite moulds collected in reddish silts and clays of Campanian-Maastrichtian age, found in the lower part of the Taveiro Formation (Taveiro, Coimbra, West Central Portugal). The known occurrences of this new species are restricted to the type locality. The main differences from other contemporaneous Anadromidae are the profuse spiral sculprure of the body-whorl, with 20-22 sub-equal, close, and regular ribs.
