8. There is, however, clear evidence for a marked shift towards wet climate at the beginning of the Holocene [9.8.4]. This period is well-documented in the form of pollen-rich thick clay sediments in Didwana and several other lakes, and its onset is dated by ¹⁴C to *c.* 10000 B.P. According to Allchin *et al.* this wet phase is represented on the younger dunes in the form of calcium carbonate concretions and root casts formed by leaching from sand in a moist climate. It is with this wet phase that these authors associate the arrival of the makers of microlithic industries. Several ¹⁴C dates obtained from these concretions at Budha Pushkar range between 6500 and 3000 B.P.
