Geography
Country:Pakistan
Coordinates: 25.3° North, 63.3° East (view map)
Paleocoordinates:23.8° North, 63.2° East (Wright 2013)
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 Miocene
Age range of interval: 11.63 - 5.333 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: Unknown position within Mekran beds.
Lithology and environment
Primary lithology: poorly lithified "siliciclastic"
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Unknown, but presumably siliciclastic. 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.
