The Amb Formation has been assigned to the artinskian
age on the basis of the relative age of parafusulina kaetensis (Kummel and Teichert, 1970).
These authors believe this sequence to be middle Artinskian
Balme  found rich and highly diversified assemblage of Potonieisporites from Amb Formation (Permian Artinskian
) Salt Range, Pakistan, exhibiting great range of variations with respect to the morphology of corpus, monolete mark and saccus, and regarded them to be belonging to the same population of Potonieisporites novicus Bharadwaj.
Thus, the unit accumulated near the limit between the Lower Artinskian
and the Upper Sakmarian, Cisuralian, Permian.
On the basis of fusulinids (first foraminifera appearing in Pakistan in Amb Formation) and different sedimentary structures observed, it is considered that Amb Formation of Central Salt Range, Pakistan was deposited in a shallow marine environment during Late Permian (Artinskian
The age of the Hillsborough River Formation was given by van de Poll (1989) as early Permian (Artinskian
Selective disappearance and replacement of different faunal groups, especially great changes in rugose corals, have been recorded from the Late Sakmarian to Late Artinskian
Petrographic study reveals feldspathic wacke in Warchha Sandstone.On the basis of previous literature the assigned stages are; Artinskian
to Warchha and Kungurian to Wordian stage to Sardhai Formation.
Early Permian (Artinskian
) sediments of Australia are also rich in Protohaploxypinus amplus .
--Neostreptognathodus pequopensis-Hindeodus minutes assemblage zone (Artinskian
This means an age included in a large interval: Middle Asselian to Middle Artinskian
The record of Monodiexodina kattaensis a larger benthic foraminiferal species in the Amb Formation indicates Late-Permian (Artinskian
) age (Dunbar 1933; Teichert 1966; Douglas 1968).
