Chitonozoans from the Ordovician Los Azules formation, Central Precordillera, Argentina

Chitinozoans from the Los Azules Formation, central Precordillera of Argentina are documented. The formation is divided into three members. Two chitinozoan assemblages are recognized: The late Llanvirn Lower Los Azules Palynological Assemblage in the middle member includes smooth forms, while the ea...
