wheel is introduced, and they show more intricate designs and also animal motifs. The characteristic female figurines appear beginning in Period IV and the finds show more intricate designs and sophistication. Pipal leaf designs are used in decoration from Period VI. Some sophisticated firing techniques were used from Periods VI and VII and an area reserved for the pottery industry has been found at mound MR1. However, by Period VIII, the quality and intricacy of designs seem to have suffered due to mass production, and a growing interest in bronze and copper vessels. Sothi-Siswal culture (4600 - 3200 BCE ) along paleo Sarasvati in Haryana and Northwestern Rajasthan Sothi-Siswal is the site of a Pre-Indus Valley Civilisation settlement dating to as early as 4600 BCE. Sothi culture may be as early as 4600 BCE, while the earliest Siswal A layer is dated 3800-3200 BCE, and is equivalent to the Middle and Upper layers of Sothi. Sothi culture precedes Siswal culture considerably, and should be seen as the earlier tradition. Sothi-Siswal culture is named after these two sites, located 70 km apart. As many as 165 sites of this culture have been reported. There are also broad similarities between Sothi-Siswal and Kot Diji ceramics. Kot Diji culture area is located just to the northwest of the Sothi-Siswal area. Type sites are Siswal in Hisar district of haryana and Sothi in Rajasthan along the Ghaggar–Chautang rivers (identified with paleo Sarasvati-Drishadvati in Vedic texts) in the Ganga–Yamuna doab, with least 165 Sothi-Siswal sites identified with this culture including Nawabans, 2 sites are bigger than 20 hectares. Sothi-Siswal ceramics are found as far south as the Ahar-Banas culture area in southeastern Rajasthan. Rangpur culture (3000 - 800 BCE) in Gujarat Rangpur culture, near Vanala on Saurashtra peninsula in Gujarat, lies on the tip between the Gulf of Khambhat and Gulf of Kutch, it belongs to the period of the Indus valley civilization, and lies to the northwest of the larger site of Lothal. Trail Diggings were conducted by Archeological Survey of India (ASI) during 1931 led by M.S.Vats(madho svarup vats). Later, Ghurye (1939), Dikshit (1947) and S.R.Rao (1953–56) excavated the site under ASI projects. S.R.Rao has classified the deposits into four periods with three sub periods in Harappan Culture, Period II with an earlier Period, Microlithic and a Middle Paleolithic State (River sections) with points, scrapers and blades of jasper.
