The genera Hysteroceras Hyatt and Dipoloceras Hyatt (Ammonoidea) in the Upper Albian of Patagonia, Argentina

The ammonite genera Hysteroceras Hyatt and Dipoloceras Hyatt are described from Patagonia for the first time. Three species are recognized from the Rio Mayer Formation in Estancia La Vega, including Hysteroceras leanzai sp. nov., Dipoloceras elegans Haas and Dipoloceras cristatum (Brongniart). Compa...
