Also known as Napak I, IV, V, IX, X
Where: Uganda (2.1° N, 34.2° E: paleocoordinates 1.7° N, 32.1° E)
• coordinate based on political unit
• local area-level geographic resolution
When: Burdigalian (20.4 - 16.0 Ma)
• "localities I, IV, V, and IX are intercalated with volcanic tuffs... and biotites from these tuffs at Napak I have produced dates of 19.5 +/- 2 Ma and 18.3 +/- 0.4 Ma" after being "adjusted for new constants" but "the younger date is discrepantly low" so an age of "between 19 and 20 Ma" (i.e., Burdigalian) is favored (Rossie and MacLatchy 2006)
• member-level stratigraphic resolution
Environment/lithology: "floodplain"; lithology not reported
Size classes: macrofossils, mesofossils
Collected by W. W. Bishop in 1958 - 1964
