Systematics, Paleobiogeography, and Paleoenvironmental Significance of Rodents from the Ibole Member, Manonga Valley, Tanzania

The late Miocene and Pliocene fossil record documents important changes in rodent faunal composition heralding the advent of the modern East African fauna. Most significant among these changes is the beginning of the radiation of the Murinae, the true rats and mice, whose earliest African record is 12–10 Ma, and which currently dominate rodent assemblages in sub-Saharan Africa. The rodent record for the late Miocene and Pliocene is better than that for the middle Miocene, but still woefully inadequate. Hence the significance of late Neogene rodent remains from the Manonga Valley, in north-central Tanzania.
