Where: Pakistan (25.3° N, 63.3° E: paleocoordinates 23.4° N, 61.9° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Mekran Formation, Late/Upper Miocene (11.6 - 5.3 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: Unknown position within Mekran beds.
• group of beds-level stratigraphic resolution
Environment/lithology: coastal; poorly lithified siliciclastic sediments
Size class: macrofossils
