Evidence of 'lost' river that ran through Thar Desert 1,72,000 years ago found

Researchers have found evidence of a 'lost' river that ran through the central Thar Desert, near Bikaner, as early as 1,72,000 years ago. The findings published in the journal Quaternary Science Reviews represent the oldest directly dated phase of river activity at Nal Quarry in the central Thar Desert. The river would've offered a lifeline to Paleolithic populations, researchers said.
