“…Our estimate of tribal divergence corresponds to this epoch and is consistent with the presence of an Asian representative ( Golunda ) as a primitive member within the Arvicanthini. Furthermore, an extinct arvicanthine genus ( Saidomys ) is known to have occurred in both Africa and Asia within that time frame: the Upper Miocene of East Africa (Winkler, , ); Early Pliocene of Pakistan and Afghanistan (Brandy, Sabatier & Jaeger, ; Sen, ); and Late Pliocene of Thailand (Chaimanee, ). The Upper Miocene also corresponds to an aridification episode and the spread of C4 grasses into East Africa (Cerling et al ., ).…”

Phylogenetic position of the endemic Mount Oku rat,Lamottemys okuensis(Rodentia: Muridae), based on molecular and morphological data

Lamottemys okuensis Petter, 1986, is restricted to the Mount Oku montane forest in the central-northern part of the Cameroon Volcanic Line (CVL; Central West Africa). It is endangered and has a decreasing population trend. The genus is monotypic and little is known about its phylogeny and evolutionary history. Using both molecular and morphological evidence, we tested two competing systematic hypotheses involving Lamottemys: whether it is more closely related to Desmomys or to Oenomys. We also discuss Lamottemys' biogeographical origin. Molecular phylogenies indicated a sister-group relationship with the Ethiopian montane forest endemic genus Desmomys. This reinforces the hypothesis of recurrent connections over time between West and East African mountains, probably facilitated by climate changes that led to expansions and contractions of montane environments. Our molecular dating, consistent with a period of intense volcanic activity in Central East Africa and the CVL, suggests that the geological history of East and Central Africa also contributed to promoting the isolation of Lamottemys in the CVL. Moreover, this study provides the most comprehensive phylogenetic analysis for the whole tribe Arvicanthini, sampling 17 of the 18 member genera. In this rodent group, stephanodonty probably appeared independently with grasses expansion. These habitat changes probably promoted the evolution of specialist rodents able to feed on abrasive vegetal matter by a dental adaptation.

“…Our timescale indicates that the migration of the ancestor of the extant Nannomys from Asia to Africa might have taken place between 8 and 6 Mya. Palaeontologists suggest that this period coincides with the existence of a palaeobiogeographical province at the Mio‐Pliocene limit extending from East Africa to India, which could have favoured such migrations through the Arabian peninsula (Brandy, Sabatier & Jaeger, 1980; Tchernov, 1992; Flynn & Jacobs, 1999). In effect, between 7 and 5 Mya, an important faunal turnover in mammals occurred in Africa (Thomas, 1984; Winkler, 1994; Leakey et al ., 1996; Hill, 1999), which is interpreted to be the result of exchanges with Asia and environmental modifications due to the elevation of the East African rift (Partridge, Wood & deMenocal, 1995).…”

Regarding murine rodents, palaeontological evidence indicates that the fossil genus Saidomys migrated from Asia to Africa through the Arabian peninsula before 6 Mya (Brandy et al ., 1980; Winkler, 1994, 1997, 2002), suggesting that the ancestor of Nannomys could have gone the same way. Environmental modifications may have been involved in the important radiation within Nannomys between 6 and 3 Mya, as observed in other African Murinae such as the Mastomys–Praomys complex (Lecompte, Granjon & Denys, 2002).…”

The genus Musencompasses at least 38 species divided into four subgenera: Mus, Pyromys, Nannomys and Coelomys. The subgenus Mus, which comprises the house mouse and related species, is by far the most extensively studied, although the subgenus Nannomys is the most speciose. Although the relationships within the subgenus Mus are rather well characterized, those between subgenera are still unclear. In the present study, phylogenetic analyses of the whole genus were performed using a larger species sample of Nannomys than in previous studies, and a nuclear gene (IRBP) in addition to mitochondrial data (cytochrome b and 12S rRNA). Members of the Acomyinae and Murinae were used as outgroups. Separate and combined analyses were performed with maximum parsimony, maximum likelihood and Bayesian methods, and divergence times were estimated. The results showed that the monophyly of the genus Mus and of each subgenus was strongly supported by the three genes and the combined analysis. The phylogenies derived from the three genes were on the whole congruent; however, several conflicting topologies were observed such as the relationships between the three Asian species of the subgenus Mus (caroli, cervicolor and cookii). Increasing the taxonomic sampling of Nannomys did not satisfactorily improve the resolution of relationships between the four subgenera. In addition, molecular calibrations indicate that the Mus and Nannomys radiation coincided with major environmental changes. © 2005 The Linnean Society of London, Biological Journal of the Linnean Society, 2005, 84, 417–427.

“…The study of fossil murids in the Indian subcontinent was initiated by [3][4][5][6] and followed by [2] who made significant contribution to the study of Pakistan Siwalik by describing various murid taxa. Subsequently, a sizeable work on the Afghanistan murids was done by [7][8][9][10][11]. As far as the Indian murids are concerned, a number of researches, e.g.…”

A new species of fossil Mus (Muridae, Rodentia) is described from the Pleistocene fluviatile deposits of the Narmada valley (Central India). The species, Mus narmadaensis sp. Nov., has a comparatively smaller lower molar which is characterized by a narrow molar with well connected cusps, small anterior expansion of lingual anteroconid, protoconid and metaconid, reduced posterior cingulum in addition to hypoconid and entoconid nearly at the same level. The large M 3 has centrally placed bulbous hypoconid. Among the extant species, the present one is closest to M. shortridgei in having similarly placed protoconid and metaconid in M 1 and a well developed hypoconid in M 3 .
