Where: Argentina (51.6° S, 72.3° W: paleocoordinates 54.0° S, 62.7° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Cerro Dorotea Formation, Paleocene (66.0 - 56.0 Ma)
• LITHOSTRATIGRAPHY: From Formación Cerro Dorotea, which (?) overlies Formación Cazador and is overlain by Formación Rio Turbio. AGE: Paleocene. The authors consider to the fauna of contained gastropods in all these levels as of age probably Paleocene by their affinities to the Salamanca and Wangaloa formations. STRATIGRAPHIC POSITION: Composite list for formation.
• formation-level stratigraphic resolution
Environment/lithology: marine; siliciclastic sediments
Size class: macrofossils
Preservation: cast, mold/impression
Collection methods: REPOSITORY: Not stated. COLLECTOR: Multiple collectors, possibly including Hünicken and Griffin.
