Murinae is the largest known subfamily of Muridae and includes 15 tribes 3 genera (incertae sedis). Although phylogeny has been studied, its phylogenetic relationships have not completely elucidated. We used framework molecular dating methodologies with vast majority available mitochondrial genomes to disentangle evolutionary history Murinae. Sixteen were identified within subfamily. Among these, fifteen found be consistent those currently recognized. Hapalomyini (Clade A) was located at base clade strong nodal support contrary previous studies, which showed that Phloeomyini diverged first. The Clade B consisted Micromyini, Rattini, genus Vernaya.

There is an ongoing debate about the internal systematics of today’s group hamsters (Cricetinae), following new insights that are gained based on molecular data. Regarding closely related fossil cricetids, however, most studies deal with only a limited number genera and statements their possible relationships rare. In this study, 41 species from Late Miocene to Pliocene, belonging seven extinct cricetine genera, Collimys , Rotundomys Neocricetodon Pseudocricetus Cricetulodon Apocricetus Hattomys analysed in phylogenetic framework using traditional maximum parsimony Bayesian inference approaches. Following thorough model testing, relaxed-clock analysis performed under tip-dating estimate divergence times simultaneously. Furthermore, so-called ‘rogue’ taxa identified excluded final trees improve informative value shown relationships. Based these resulting trees, fit topologies stratigraphy assessed ancestral states characters reconstructed parsimonious approach stochastic character mapping. The overall approaches largely congruent each other confirm monophyly genera. Additionally, synapomorphies can be for state reconstructions.
