Earliest Records of the Genus Spiticeras Uhlig in the Neuquén Basin, Argentina: Systematic and Biostratigraphic Implications

The earliest records of the genus Spiticeras Uhlig in Western Gondwana occur in the Upper Jurassic-Lower Cretaceous deposits of the Vaca Muerta Formation in the Neuquén Basin, Argentina. Those records involve two species, Spiticeras acutum Gerth and Spiticeras hauthali Gerth, which were firstly desc...
