Since these findings occur in isolation from hilly terrain and flood plains amidst deep forest they are mostly secondary in nature and their cultural horizon is to be assessed in chronological framework. A scientific dating is also to be probed which is the need of the hour. The data obtained by various scholars on the prehistoric researches assist in evolving a chronological frame work pertaining to the North-east region. As far as historical archaeology is concerned, there are very few sites found excavated in this region as yet.
Recently structural evidence encountered at Ambari excavation in Guwahati from the lowest level appears to be of Sunga-Kushana period. It is first time that an antiquity of the site has been pushed back to the Sunga-Kushana period in the region. However, the water logging at this level hampered further probing. Since the region is referred in epics and Puranas as Pragjyotishpur occurrence of material culture pertaining to the much earlier period in further excavations cannot be ruled out. The workshop aimed to delve upon the recent prehistoric and historical investigations carried out by various eminent scholars in this region. It made them to share and interact with each other their valued opinions, views and theories and also assisted in establishing well defined chorological framework pertaining to the prehistoric and historic times prevailed upon in bygone era in this region.
