New muroid rodent and Sivapithecus dental remains from the Lower Siwalik deposits of Ramnagar (J&K, India): Age implication

Cricetid rodents from the Lower Siwalik Subgroup of Jammu, India: Biochronological significance

“…M. daamsi is known to occur between 13.8 and 12.5 Ma within the Chinji Formation of Pakistan (Flynn et al, 1995). Its presence in the Ramnagar region further substantiates the age assignment made for these deposits between 13.8 and 13.2 Ma by Sehgal and Patnaik (2012) in general and the Dehari fossil locality occurring in the vicinity of Ramnagar in particular as both Kanisamys cf. potwarensis Prasad, 2006) (range 14.3-13.2 Ma, Flynn et al, 1995) and M. daamsi (present work) (range 13.8-12.5 Ma, Flynn et al, 1995) come from this site (Fig.…”

“…This discrepancy, however, seems to be an artefact of sampling bias (and accompanying screen washing techniques) as shown by the discovery of rodents from Jammu region (Parmar and Prasad, 2006;Sehgal and Patnaik, 2012; and the present work).…”

“…potwarensis earlier reported from Dehari by Parmar and Prasad (2006), constrained the age of Ramnagar sediments between 13.8 and 13.2 Ma. The cricetid and murid specimens described by Sehgal and Patnaik (2012) come from a palaeosol layer lying just above the reference sandstone G (Fig. 1C) of Basu (2004) and Kanisamys cf.…”

“…Based on this fossil find along with the recovery of a muroid rodent Antemus chinjiensis and an earlier report of a murid rodent, Kanisamys cf. potwarensis (Parmar and Prasad, 2006) from the Ramnagar area, Sehgal and Patnaik (2012) Parmar and Prasad (2006). We here add another rodent, Megacricetodon daamsi to the list of rodents recovered from the Dehari locality.…”

Neogene Climate, Terrestrial Mammals and Flora of the Indian Subcontinent

“…These taxa are found today in high rainfall regions either in the Western Ghats or in northeast India (Srivastava et al, 2014). A good number of plant megafossils in the form of woods and leaves were described from Middle Siwaliks of Nalagarh and Jawalamukhi (Prasad, 2006 (Sehgal and Patnaik, 2012;Parmar et al, 2015 (Parmar et al, 2015). In the northeast the Garo Hills, Assam have yielded Microbunodon silistrensis suggesting a late early Miocene (17.8 Ma) to middle Miocene (11.4 Ma) age (Patnaik, 2016 and references therein).…”
