Original: The proposition of grouping these sites as an '' independent Bronze Age civilization with its own architecture and language '' , intermediate between Elam to the west and the Indus Valley Civilization to the east , is due to Yousef Majidzadeh , head of the archaeological excavation team in Jiroft .
Simplified: The Jiroft site itself is of undisputed notability as a mid-3rd millennium city situated between the Elamite civilization to the west and the Indus Valley civilization to the east .
