Also known as ETE Locality 1058, Lothagam 1, Lothagam 1C, Lothagam, Lothagam - Apak Mb, Nachukui Formation

Where: Kenya (2.9° N, 36.1° E: paleocoordinates 2.7° N, 35.6° E)

• coordinate stated in text

• local area-level geographic resolution

When: Apak Member (Nachukui Formation), Zanclean to Zanclean (5.3 - 2.6 Ma)

• K-Ar dating constrains the base of the Apak Member to be older than 4.22 +/- 0.03 Ma (from altered pumices 35 m above the base of the Apak Member) and younger than about 5 Ma (4.9 Ma is suggested). The top of the Apak Member is the Lothagam Basalt, which has been dated (K-Ar) to 4.2 +/- 0.03 Ma.

• member-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; poorly lithified sandstone and poorly lithified, paleosol/pedogenic mudstone

Size classes: macrofossils, mesofossils

Collection methods: bulk, surface (in situ), mechanical, sieve,
