Albian heteromorph ammonoids from southern Patagonia, Argentina

Representives of the ammonoid families Anisoceratidae Hyatt, 1900, and Labeceratidea Spath, 1925, are locally common in Albian deposits of the Austral Basin, southern Patagonia, Argentina. Examination of abundant anisoceratid material documents extensive intraspecific variation. The following specie...
