A heteromorphous ammonite (Spiroceratidae) of Upper Bajocian age from Paso del Espinacito, San Juan, Argentina
The species Spiroceras orbignyi (Baugier y Sauze) is recorded from the upper levels of the Los Patillos Formation in the Paso del Espinacito area, Principal Cordillera of San Juan. S. orbignyi shows a widespread geographic distribution but is stratigraphically restricted to the Upper Bajocian. In th...
