This chapter analyzes the fossil record of South Asia's Neogene small land mammals in the context of its paleobiogeography. Within the Indian Subcontinent, high faunal similarity can be observed among local small mammal assemblages distributed on a scale of 1000 kilometers, and these are distinct from assemblages to the west and northwest and northeast, beyond the subcontinent. Eastward into Thailand, Myanmar (Burma), and Yunnan, China, faunal similarity with the Indian Subcontinent is apparent but weaker than within the subcontinent. This pattern mimics the distribution of the present-day Oriental biogeographic province. This chapter examines the extent to which this paleozoogeographic pattern can be defined, as well as faunal elements that do not follow the rules. Evidence from Yunnan, Thailand, and Myanmar shows that many genera of small mammals are shared throughout southern Asia.
