Desmoceratidae, Silesitidae and Kossmaticeratidae (Ammonitida) from the Upper Aptian-Albian of Patagonia (Argentina)

Upper Aptian-Albian Desmoceratidae, Silesitidae and Kossmaticeratidae of the Patagonian Andes are revised taxonomically and chronologically, based on the re-examination of all available specimens and of most Aptian-Albian localities of Santa Cruz Province, Argentina. Types and figured specimens of p...
