"At this time (c. 2150-2000 BC) ivory from Meluḥḥa is mentioned only in connection with ivory bird figurines. Otherwise, in the body of texts from Ur dating to about 2000 BC ivory is attributed to Dilmun (Bahrain), where it had presumably been shipped up the Gulf from the Indus, where ivory was plentiful on the sites of the Harappan period, both as tusks and as objects."
