Where: Antarctica (64.2° S, 56.6° W: paleocoordinates 63.4° S, 63.7° W)

• coordinate estimated from map

When: Cucullaea I Member (La Meseta Formation), Ypresian (56.0 - 47.8 Ma)

• The humerus MLP 13-IX-28-385 was collected at the fossil locality IAA 2/13 (also informally known as “Simil RV”) which encompasses outcropping levels of Cucullaea I Allomember (Ypresian). These beds are correlated with DPV 6/84 (= RV 8200 for woodburne & zinsMeister, 1984), belonging to levels deposited above to the Naticid gastropods levels.

Environment/lithology: marine; sandstone
