Basic information
Sample name: Dehari
Reference: V. Parmar, G. V. R. Prasad, and R. Norboo. 2018. Middle Miocene small mammals from the Siwalik Group of Northwester India. Journal of Asian Earth Sciences 162:84-92 [ER 4081]
Geography
Country: India
State: Jammu and Kashmir
Coordinate: 32° 47' N, 75° 17' E
Coordinate basis: estimated from map
Scale: quarry
Formation: Mansar
Time interval: Middle Miocene
Zone: MN6
Geography comments: "from a single locality... about 0.5 km northeast of Dehari village on Ramnagar-Dhar road"
coordinate estimated from map in Fig. 1C
"an age of about 13.6–13.2 Ma is inferred for the rodent yielding horizon at Dehari" based on a miscalculation of ranges for these taxa based on data for the Siwalik Group of Pakistan: the actual concurrent range zone is 13.6 to 12.0 Ma, essentially MN6 and definitely Middle Miocene
