Protovirgularia dichotoma-protovirgularia rugosa: An example of a compound trace fossil from the lower cretaceous (Agrio formation) of the Neuquén basin, Argentina

This study focuses on the description of a compound trace fossil from the Cretaceous of the Neuquén Basin, Argentina. This structure comprises two discrete ichnotaxa: Protovirgularia cf. dichotoma M'Coy, 1850, and Protovirgularia cf. rugosa (Miller and Dyer, 1878). Open nomenclature is chosen d...
