Where: Pakistan (24.9° N, 67.1° E: paleocoordinates 19.2° N, 66.4° E)
• coordinate stated in text
• local area-level geographic resolution
When: Gaj Formation, Early/Lower Miocene (23.0 - 16.0 Ma)
• STRATIGRAPHIC RELATIONS: From the lower Gaj beds, which regionally overlie the Nari beds (Oligocene) and are overlain by the Middle-Late Miocene Mekran beds. AGE: The Gaj Formation is primarily Burdigalian, except for the basal parts (Naseem et al. 1996). Larger foraminifera are characterized by Miogypsina gunteri and M. thecideaeformis zones (Aquitanian and Burdigalian, early Miocene) (Kureshy, 1982). STRATIGRAPHIC POSITION: from the lower Gaj beds.
• group of beds-level stratigraphic resolution
Environment/lithology: poorly lithified limestone
Size class: macrofossils
