The Early cretaceous (Valanginian) ammonite Chacantuceras gen. nov. - A link between the Neuquén and Austral basins

Chacantuceras gen. nov. (type species: Neocosmoceras ornatum Olivero 1983) is proposed to embrace some Late Valanginian trituberculate neocomitid ammonites from the Neuquén and Austral basins that have been assigned previously either to the mid Berriasian genus Neocosmoceras or to the Early Hauteriv...
