At which Harappan sites Bone tools, which are not indigenous to India, were found?

Bone tools have been unearthed at the Harappan sites of Chirand, Gufkral and Burzahom, which were likely imported from outside. Evidence shows links between Harappans and Neolithic people farther west in Afghanistan and Central Asia where bone tool technology was common, but not prevalent in early farming cultures of North India. The presence of non-local raw materials like lapis lazuli also indicate the Harappans were well connected to other cultures and established extensive trade networks.
