A systematic taxonomic study of fossil giraffids and associated fossil fauna of rhinoceros, bovids and
tragulid has been described here from the Chinji Formation, Lower Siwaliks of Pakistan. The collected specimens
belong to the four species: Giraffa priscilla, Gazellalydekkeri, DorcatheriummajusandGaindatheriumvidalifrom the
outcrop of Dhok Bun AmeerKhatoon and ChabbarSyedan fossil localities of Chakwal and Jhelum district
respectively which belongs to the Late Miocene in age.

These localities are very rich and the skull of G. priscilla
containing right and left complete series of upper dentition has been reported first time from the outcrops of DBAK.
The rhinoceros fossils of G.vidaliwere recovered from the ChabbarSyedan, Chinji Formation of Lower Siwaliks.
The fossil remains of G. lydekkeri and D. majusare also recovered from the DBAK. The current studies have been
conducted by comparison of morphometric characteristics of already studied specimens. Paleoenvirnment,
biogeography and feeding habits suggested the presence of abundant forests, herbaceous, grassy and bushy
vegetation in the outcrops of ChabbarSyedan and DBAK. On the basis stratigraphy it is suggested that both
localities have same Late Miocene age.
