Description

The fossil record of murine rodents from Siwalik Group rocks in Pakistan appears to document (1) the origin of murines in southern Asia at about 13.75Ma, (2) the attainment of an essentially modern grade of dental morphology by 11.8Ma, and (3) the first record of the modern genus Mus by 5.7Ma. Both anagenesis and cladogenesis are documented in the Siwaliks. Surprisingly, Siwalik murines are never particularly diverse at any given site (four species or less). The extant diversity of the group is probably the result of iterative emigration events originating from southern Asia accompanied by subsequent geographically restricted radiations.
