Hakra Ware culture

"Mughal (1990, 1997) considers the Hakra culture to be earlier than Kot Dijian, now designated as Early Harappan by Mughal and others, and earlier than the Harappan. That may be correct. It is also quite likely that some Hakran settlements, like related Kot Dijian ones, persisted and were contemporary with, or even later than, the Harappan (Shaffer 1992). Only more archaeological fieldwork excavations and radiometric dates may resolve these issues."
