“…Carditids are associated with dense concentrations of the gastropod Rostellaria rothi Ihering, 1903 and the oyster Cubistostrea ameghinoi (Ihering, 1902) (Cantera Cholino samples 15 and 17, respectively), and of turritellids in Picada Sísmica, where the carditids are found alone with the infaunal soft-bottom dewelling bivalves Neilo sp. and Dosinia burckhardti Ihering, 1907(del Río et al, 2011 Carditids are rare at Cerro Bayos, where only one species has been found. Material comes from basal (CB31 and CB32 samples) and uppermost limestones (CB47 samples) of the Roca Formation where the NP1 and NP3 biozones are identified, respectively ( Fig.…”

Neprolithus frequens Górka, conocida especie diácrona, caracteriza asociaciones de altas latitudes durante el Maastrichtiano (Wind y Wise, 1976;Wind, 1979) y su aparición conjuntamente con la primera aparición (FO) de Cribrosphaerella daniae Perch-Nielsen caracterizan el Maastrichtiano Tardío (Perch-Nielsen, 1985a;Bernaola y Monechi, 2007).…”
