Geography
Country: | Pakistan |
Coordinates: | 25.3° North, 63.3° East (view map) |
Paleocoordinates: | 23.4° North, 61.9° East |
Basis of coordinate: | based on nearby landmark |
Geographic resolution: | local area |
Time
Period: | Neogene | Epoch: | Miocene |
10 m.y. bin: | Cenozoic 6 | ||
Key time interval: | Late/Upper Miocene | ||
Age range of interval: | 11.63000 - 5.33300 m.y. ago |
Stratigraphy
Formation: | Mekran | ||||
Stratigraphic resolution: | group of beds | ||||
Stratigraphy comments: 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: Base of sandstones. |
Lithology and environment
Primary lithology: | poorly lithified sandstone |
Includes fossils? | Y |
Lithology description: SPECIFIC LITHOLOGY: Sandstone. LITHIFICATION: Poorly-lithified, based on figured specimens. | |
Environment: | coastal indet. |
Geology comments: ENVIRONMENT: Not stated in text, but presumably shallow shelf siliciclastic. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils |
Collection methods and comments
Collection methods: | surface (in situ),field collection |
Reason for describing collection: | taxonomic analysis |
Collectors: | Vredenburg |
Collection method comments: COLLECTORS: Multiple collectors including W. Blanford, Wynne, Hira Lal, Ram Singh, and Noetling (staff of Geological Survey of India) during the early 1900's. REPOSITORY: Geological Survey of India, with voucher specimens possibly at the BMNH. | |
Taxonomic list comments:COVERAGE: Exhaustive for gastropoda, bivalvia, and scaphopoda. NOMENCLATURE: Antiquated, but from an authoritative publication, with use of species and subgenus resolution assignments. Nomenclature can be updated through reference to Harzhauser and Swarko publications. |
