Abstract:
The genus Hippopotamodon is the largest known Siwalik suid. The cheek teeth are relatively simple, bunodont and brachyodont. The post-talon is complex and multituberculated. Premolars are normally inflated with a long diastema between P1 and P2. The premolars and molars are thickly cingulated and provided with many additional accessory conules. The suid grooves are moderately present on the molars. The posterior choanae is u-shaped and open immediately behind M3 The male Hippopotamodon has very large flaring, triangular canine. Its lateral side is completely covered by the enamel. The lower incisor is strongly keeled. P4is provided with posterior accessory conules which are almost as large as two main labial cusps, the anterior and posterior cusps on the P3_4are very high. The species Hippopotamodon sivalense ranges from Nagri to Hasnot through Dhok pathan. Its known range is about 7 to 10 million years, i.e., Miocene age which is quite similar in range to Hipparion, Propotamochoerus and Microstonyx. The ancestors of Hippopotamodon sivalense evolved in Europe and eventually migrated to South Asia.
