New remains of Propotamochoerus hysudricus are described from localities of the Dhok Pathan and Nagri formations of the Middle Siwaliks of Pakistan. Propotamochoerus hysudricus is a moderate-sized extinct suid with comparatively larger cheek teeth, elongated first molar, and basal pillars. The Propotamochoerus hysudricus material described in this article is a good addition in the field of paleontology as these new remains comprise of the maxilla, mandibles, isolated incisors, and canine along with premolars and molars. The genus Propotamochoerus in the Siwaliks is represented only by a single species, i.e., Propotamochoerus hysudricus. Its closest relative Korynochoerus is found in Eurasia. The age range of the species is from about 10 million to about 6 million years. The probable ancestor of Propotamochoerus is Hyotherium of Chinji times about 11 million years ago. The primitive genus Propotamochoerus was pretty near to the Palaeochoerus and was treated as a precursor of other suinae. Ancient Propotamochoeroid stock gave rise to three major groups, one leading to genera Potamochoerus and Sus , the other to the genera Hippohyus and Sivahyus, another leading to the genera Microstonyx , Hippopotamodon , and Jhelumia. The major difference between Propotamochoerus hysudricus and other species of the genus Propotamochoerus is mainly the dental morphology of premolars.
