Where: Pakistan (25.2° N, 64.6° E: paleocoordinates 24.2° N, 63.9° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Mekran Formation, Early/Lower Pliocene (5.3 - 3.6 Ma)
• STRATIGRAPHIC RELATIONS: Overlies the Gaj beds. AGE: Somewhat unclear. Younger than Early Miocene Gaj beds (Aquitanian-Burdigalian), and younger than the Gwadar beds (Pliocene), so probably ranging from Middle to Late Miocene in age. Age will be amended following consideration of taxonomic similarities with Indonesian faunas. STRATIGRAPHIC POSITION: Nodular shales.
• group of beds-level stratigraphic resolution
Environment/lithology: coastal; poorly lithified, concretionary shale
Size class: macrofossils
Collected by Vredenburg
