Answer 2

this is the period which was called Pre-Harappan in the Farmana excavation report published last year (Shinde et.al. 2008b). However, after evaluating its contribution to the development of Mature Harappan phase, it was clear that most of the elements of this phase continued in the succeeding phase as it is or with minor modifications. It is because of this that this early phase is treated as a formative stage of the Harappan Culture and hence the term Early Harappan. The last three layers at the site (Layers 10-12) belong to the Early Harappan phase (Period- I). The following are some of the AMS dates from the Early Harappan levels from Frmana, Girawad and Mitathal:

These dates are not consistent and hence are not of much use to decide the general chronology of Period-I. There are a number of dates from the early occupation at the site of Bhirrana, which is the closest to Farmana and Girawad. Most of the dates for this period are quit early in age at Bhirrana. It is therefore safe to presume that the Early Harappans flourished in this part in the middle of 4th millennium BC and continued until the emergence of the Mature Harappan phase around 2600 BC.
