Where: Argentina (51.0° S, 72.0° W: paleocoordinates 53.5° S, 62.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Man Aike Formation, Middle Eocene (47.8 - 37.7 Ma)
• STRATIGRAPHIC RELATIONS: From the Man Aike Fm, which regionall unconformably overlies the Late Cretaeous Calafate Formation. THICKNESS: from several beds within 40-45 m thick section.

Placed in Middle Eocene pending revised age. STRATIGRAPHIC POSITION: From beds in upper part of section.
