Paleoenvironmental interpretation of Turritelline gastropod-dominated assemblages from the La Meseta formation (Upper Eocene), Seymour Island, Antarctica
Turritellid gastropods (family Turritellidae ) are common components of many benthic marine assemblages of Late Jurassic to Recent age worldwide. This study focuses on turritellid-dominated assemblages (TDAs) from the La Meseta Formation on Seymour Island from the middle to late Eocene of Antarctica...
