Oli, Krishna Prasad |
The Siwalik (Churiya) range is a fragile land system formed from sediments during the raising of the greater and lesser Himalaya. The area is considered one of the world's most important sources of the later tertiary fossils of mammals and provides a basis for much of our current knowledge about the evolution of fauna, especially primates and reptiles. The Siwaliks, ranging east to west, occupy an estimated 13; of Nepal's total land area.
