New trace fossils from the La Meseta Formation [Eocene] of Seymour Island, Antarctica

Trace fossils Lockeia siliquaria James, Ophiomorpha nodosa Lundgren, Para- taenidium seymourensis isp. n., Protovirgularia rugosa (Miller and Dyer) and Rhizo- corallium jenense Zenker have been described for the first time from the Eocene La Meseta Formation of Seymour (Marambio) Island, Antarctic Peninsula. Determinations of some trace fossils formerly described from this formation have been revised. The whole trace fossils association from the La Meseta Formation points to foreshore-offshore environment as indicated by presence of the Skolithos and Cruziana ichnofacies, and to at least temporal normal salinity.
