“…1). This location is part of the same small area of exposures where previously described specimens from Dehari were mapped (Parmar and Prasad, 2006;Parmar et al, 2015Parmar et al, , 2017Singh et al, 2018) and are from the same general stratigraphic position. Lithologically, the sites are dominantly characterized by red to reddish-brown mudstones alternating with thick, fine-grained, gray sandstones.…”

“…An age for Dehari at the older end of this range also would be consistent with previous reports of Megacricetodon daamsi (LAD ca. 12.5 Ma on the Potwar Plateau; Flynn et al, 1995) from the locality (Parmar et al, 2015). The only reported rodent taxon known from Dehari that would appear at odds with an age of ca.…”

The fossil record of treeshrews, hedgehogs, and other micromammals from the Lower Siwaliks of India is sparse. Here, we report on a new genus and species of fossil treeshrew, specimens of the hedgehog Galerix, and other micromammals from the middle Miocene (Lower Siwalik) deposits surrounding Ramnagar (Udhampur District, Jammu and Kashmir), at a fossil locality known as Dehari. The treeshrew from Dehari (Sivatupaia ramnagarensis n. gen. n. sp.) currently represents the oldest record of fossil tupaiids in the Siwaliks, extending their time range by ca. 2.5–4.0 Myr in the region. Dietary analyses suggest that the new tupaiid was likely adapted for a less mechanically challenging or more frugivorous diet compared to other extant and fossil tupaiids. The occurrence of Galerix has only been recently documented from the Indian Siwaliks and the Dehari specimens help establish the likely presence of a relatively large Siwalik Galerix species in the Ramnagar region. In addition to the new treeshrew and hedgehogs, new specimens of the rodents Kanisamys indicus, Sayimys sivalensis, and Murinae indet. from Dehari help confirm that age estimates for the Ramnagar region are equivalent to the Chinji Formation in Pakistan, most likely corresponding to the middle to upper part of the Chinji Formation.

“…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).…”

The present review compiles the work done in and around India during 2011-2015 on the terrestrial climate, fauna and vegetation changes during the Neogene. Tectonics that led to the final closure of Tethys, uplift of the Tibetan plateau, land connection between Africa and Eurasia played a major role in the climatic variability and paleobiogeographic history of fauna and flora of the Indian subcontinent. Though the timing of initiation of monsoon is still a debatable issue, establishment of seasonal reversal in wind direction pattern during summer and winter period and development of monsoonal climate in larger parts of the Indian subcontionent is characteristic of Neogene. Fossil records of flora and fauna provide evidence of warm and humid climate of early Neogene, which then shifted to cooler and drier conditions during the late Neogene. This shift in the climatic conditions resulted in a major vegetation change in the Indian subcontinent with Early and Middle Miocene being dominated by C 3 vegetation, and warm and humid tropical flora in low land areas while Late Miocene and Pliocene saw the dominance of C 4 grasslands. Influenced by this major vegetation and ecological shift around Late Miocene, several browsing mammals of the Early and Middle Miocene landscape gave way to mostly grazing mammals of the Late Miocene and Pliocene time.
