  Twenty mammalian fossil specimens of varying preservational state are described from the Chinji Formation of Dhulian, Pakistan. The remains described in this study are all teeth and represent the Proboscidea, Perissodactyla and Artiodactyla. All the dental specimens are new variants recorded here for the first time. Pliotriplopus dhulianensis is new to science having small size and absence of crista than Pliotriplopus chinjiensis. These findings extend the geographic distribution of this dentally highly derived Triplopinae, which was previously restricted to a single species, Pliotriplopus chinjiensis. Additional fossils of the three mammalian orders are necessary to shed new light on the phylogenetic relationships within the first representatives of the orders in Eurasia. A very important, deciduous tooth of the species Stegolophodon cautleyi hitherto unknown is described in this report.

  Dorcabune nagrii is a smaller species of genus Dorcabune and is known only from the Middle Siwaliks. The described specimens in this study are collected from Hasnot which is the upper part of the Middle Siwaliks include three second molars and one last molar. All the described specimens belong to the lower dentition. Dorcabune nagrii agrees with the Dorcabune latidens in respect of size but differs by the smaller breadth of molars and inferior depth of the mandible. The aim of the study is to describe Dorcabune nagrii from the upper part of the Middle Siwaliks.

  The Siwalik formations of northern Pakistan consist of (fluvial) deposits of ancient rivers that were formed from the early Miocene up to the late Pliocene. The tertiary continental deposits of the Siwaliks are highly fossiliferous with a diverse array of terrestrial and freshwater vertebrates in which ruminants are fairly abundant. The rich Siwalik fossil record presents a detailed history of the prehistoric mammals of the Indian Subcontinent. In this research it was analyzed individual well-sampled sites to study the past ruminant community. The Siwalik fossil record becomes increasingly informative for diverse research questions in paleobiology as a result of its growing and robust data set. The fossils from Pakistan may also document the first appearance and subsequent radiation of giraffes and bovids, two groups that dominate the late neogene (tertiary) as well as the modern herbivore faunas. Throughout the Siwalik formations, the ruminants are by far the most abundant mammal group. The number of ruminant species, as recorded in the tertiary hills of the Siwaliks is clearly greater than that observed in most ecosystems today, which probably indicates overall greater species richness than is typically present. Today, the ruminants constitute the largest group of ungulates, with more than 190 species and its distribution is widespread in all continents except Australia and Antarctica.
