W 86-11, Seymour Island (Eocene of Antarctica)

Where: Antarctica (64.2° S, 56.6° W: paleocoordinates 63.7° S, 61.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: La Meseta Formation, Lutetian (47.8 - 41.3 Ma)

• Location most likely places it just above the Telm5/Telm6 boundary.

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal; siliciclastic sediments

• From Stillwell & Zinsmeister (1992): For Telm6 and 7, "the sum of evidence is in support of a shallow, protected lagoonal setting with open bays behind barrier islands with tidal channels and depressions in which shell material and coarse sediment were occasionally concentrated during catastrophic events, such as storms rearranging the channels and covering regions of the lagoon bottom with new layers of silty sediments."

Size class: macrofossils
