The lower jaw of mammals, composed of only a single pair of bones, the dentaries, which articulate directly with the cranium, is unique among vertebrates. On the other hand, tdentary is only one of several bones in the lower jaw, and it usually does not articulate directly with the cranium in other vertebrates. The presence of an articulation between the dentary and squamosal is one of the characteristic features used to define Mammalia. Mammalian teeth are more diverse and complicated than other vertebrates as their diet is varied. Because of feeding variations, they exhibit great diversity in number, type, size, and shape of teeth. Many extinct mammals are discovered from fossilized teeth. The morphology of cheek teeth (premolars and molars) is one of the most important character for identification of mammals. For instance, the taxonomic studies of rodents particularly the Family Muridae needs a detailed knowledge on morphology of cheek teeth. The total number if teeth in any species remains constant but varies between species. Thus teeth have been considered as significant tools in classification and identification of mammals. This publication reviews the dentition of India's terrestrial mammals.
