ZPAL 11, Cape Wiman (Eocene of Antarctica)

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

• coordinate estimated from map

• outcrop-level geographic resolution

When: Telm 1 Member (La Meseta Formation), Ypresian (56.0 - 47.8 Ma)

• Likely Lutetian based on dinoflagellate biostrat and Sr isotopes (Douglas et al., 2014)

•See Kloess et al. 2020 for useful breakdown of stratigraphy of the La Peseta Formation

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; lithified, pebbly, sandy conglomerate and lithified, concretionary, ferruginous, calcareous sandstone

• Possibly delta or estuary deposits
• The lowermost unit Telm l crops out at Cape Wiman and west of Cross Valley. Interpreted as transgressive deposits, it is composed of a sandy pebble-conglomerate succeeded by iron-stained quartz sandstones at the westernmost exposure and of a laminated , fissile quartz sandstone with carbonate-cemented concretions associated with a megabreccia facies at the northenmost
