New dental material of cervids from Middle Siwalik deposits of Potwar Plateau, Pakistan has been described. The remains are recovered from the outcrops, situating in three districts of Punjab, namely Kaulial Kas in Attock district, Dhok Pathan in Chakwal district, and Hasnot and Padhri in Jhelum district, Punjab, Pakistan. The outcrops date to Dhok Pathan formation (Late Miocene – Early Pliocene). The identiied cervid species include Rucervus cf. simplicidens, Cervus cf. triplidens and Cervus cf. sivalensis. These specimens provide additional information about the recorded cervid species and contribute to recent work from the Middle Siwalik Hills of Pakistan. INTRODUCTION C ervids entered in the Siwaliks during the Pliocene time with their similarity to European fossil deer of Pliocene (Barry et al., 2002). The Upper Siwalik rocks of Pakistan have produced several cervid species (Arif and Raza, 1991; Khan et al., 2014). Five cervid species Rucervus simplicidens, Cervus triplidens, C. rewati, C. sivalensis and C. punjabiensis are reported from the Siwaliks (Azzaroli, 1954; Arif and Raza, 1991; Khan et al., 2014; Ghaffar et al., 2006, 2010, 2015, 2017). The studied specimens are recovered from four localities of Dhok Pathan Formation, Middle Siwalik Subgroup, including Kaulial Kas (Attock district), Dhok Pathan (Chakwal district), and Padhri and Hasnot (Jhelum district). The Dhok Pathan Formation is characterized by the light-colored sandstone with alternate clay and minor layers of conglomerates. The sediments have orange shale with less compacted gray sandstone bodies and red-brown mudstone with a few thin conglomerate interbeds. Sandstone and superposed red mudstone often form ining-upward couplets where the lower contact is erosional and lined with ripped-up clasts of the underlying mottled and red-brown clay stone. At a few places, thin crevasse-splay sheets, around 30 cm thick, clast-supported conglomerates occur. These conglomerate beds often contain unidentiiable bone and tooth fragments. * Corresponding author: babar.441@gmail.com 0030-9923/2018/0004-1489 $ 9.00/0 Copyright 2018 Zoological Society of Pakistan Sandstone beds in upper section gradually get thicker and multistoried. These substantially thicker, vertically stacked and laterally extensive individual gray sandstone units, form a ining-upward sequence with thinner dull red to brown siltstones on top (Behrensmeyer and Tauxe, 1982). Varicolored, mottled, highly bioturbated paleosol horizons, form distinct and laterally extensive units within the siltstone. The magnetic polarity and stratigraphic dating has constrained the age of the Dhok Pathan Formation to between 10.1–ca. 3.5 Ma. The lower part of the Dhok Pathan Formation is dated 10.1-9.0 Ma and the upper part is dated at ca. 9.0-5.5 Ma (Cande and Kent, 1995; Barry et al., 2002). Kulial Kas fossils have been poorly documented. Cervid remains described in the present work, and collected from this area are signiicant, as they can increase the number of biostratigraphic records of the Siwalik cervids. MATERIALS AND METHODS We performed several ield visits in order to collect the cervid fossil described. The fossils were collected carefully from the fossiliferous locations of Kaulial Kas, Dhok Pathan, Hasnot and Padhri. The identiiable fossils from the whole collection were catalogued and considered for the taxonomic study. The fossils were thoroughly washed and cleaned in the laboratory with the help of ine needles and brushes and prepared for the study. Damaged parts of the fossils were assembled with some kinds of gums (resins) such as elfy, elite, ixin, araldite and magic stone. The specimens inventory number consists of a ABSTRACT Pakistan J.
