Giraffokeryx punjabiensis (Artiodactyla, Ruminantia, Giraffidae) from Lower Siwaliks (Chinji Formation) of Dhok Bun Ameer Khatoon, Pakistan

Fossil remains of Giraffokeryx punjabiensis (premolar and molar teeth belonging to the upper and lower jaws) have been collected and discussed from Chinji Formation of Dhok Bun Ameer Khatoon (32o 47’ 26.4” N, 72° 55’ 35.7” E). All these (twenty one) specimens are isolated teeth, which provide new data and give valuable information on the biostratigrphy and paleoecology of Giraffokeryx punjabiensis as well as the stratigraphy and paleoclimates of these Miocene rocks of the Chakwal district, Pakistan.

New Fossil Remains of Giraffids from the Lower Siwaliks of Punjab, Pakistan: Evolution, Systematics and Biogeography

Taxonomic study from a late Miocene Fossil locality Dhok Bun Ameer Khatoon, Lower Siwalik Hills of Pakistan has been conducted. New fossil remains belong to family Giraffidae which include right and left maxilla, isolated upper premolars and molars. After morphological and comparative analysis, the collection is attributed to Giraffokeryx punjabiensis and Giraffa priscilla. Size variation in dentition is taxonomically important for vertebrate evolutionary point of view and this is the main reason to conduct this study at this specific site

Giraffokeryx (Artiodactyla: Mammalia) Remains From the Lower Siwaliks of Pakistan

Giraffokeryx is represented in the middle Miocene vertebrate assemblage from the Chinji Formation by 13 remains. The material comprises predominantly isolated teeth, and a few fragments of maxilla and mandible. The well preserved upper and lower dentition allows recognizing the presence of Giraffokeryx cf. punjabiensis in the Chinji Formation of the Lower Siwaliks. A detailed description of the fossils and their taxonomic classification is being provided. The validity of the new species Giraffokeryx chinjiensis Sarwar, 1990 is discussed and the
