New murids and gerbillids (Rodentia, Mammalia) from Pliocene Siwalik sediments of India.
Rajeev Patnaik
Keywords: Dental morphology; evolution; new species of murids and gerbillids; phylogenetic relationships; Systematics

    Murids and gerbillids (Rodentia, Mammalia) recovered from four Upper Siwalik localities; Moginand (around 3.5-4.5 m.y.), Kanthro (around 2.5 m.y.), Ghaggar (around 2 m.y.) and Nadah (around 1.8-2 m.y.) are described herein. A comparison of Mus linnaeusi sp. nov. reveals its close relationship towards the house mouse Mus musculus. In contradiction to earlier proposals that Golunda migrated to the Indian subcontinent from Africa sometime during Late Pliocene, it is suggested here that Golunda (in the form of Golunda tatroticus sp. nov.) evolved from Parapelomys robertsí of Late Miocene deposits of Siwaliks. Golunda tatroticus sp. nov. exhibits a progressive relationship to the extant Indian Bush Rat Golunda ellioti through Golunda kelleri and Golunda sp. Tatera pinjoricus sp. nov. is considered here to be a link between the extinct Abudhabia kabulense and the extant Tatera indica.
