Northwestern Iran is one of the key regions in the archaeological researches, especially during the Iron Age. Tepe Hasanlu is an important ancient site due to its long-term occupation and extensive excavations, with relatively complete studies. This paper dealing with the results of recent archaeozoological researches of Hasanlu, to complete the lack of studies on the subsistence economy of the site. The studied faunal remains of Hasanlu derived from campaigns of 1970, 1972 and 1974, which are housed in the Osteology Department of the National Museum of Iran. This paper intends to examine the subsistence economy and animal exploitation patterns during the Iron Age in Tepe Hasanlu. The faunal remains of Middle and Late Bronze Age and Historic period also evaluated to better perception of changes and evolutions in subsistence strategies of Iron Age. The results of studies pointed to the developed animal husbandry during all periods of Hasanlu, which domesticated sheep and goats, and cattle were the most important exploited resources. Equids also allocated the considerable portion of the collection which especially bred in Iron Age. The same pattern identified in contemporaneous sites such as Haftavan Tepe and Dinkhah Tepe in northwestern Iran.
Ziwiye, as one of the key sites for Iran’s North West Iron Age (Median kingdom), has many masterpieces kept in different museums and a long list of publications. The main part of this list consists of monographs that are written based on one or more limited objects from an out of context collection. There are few articles that comprehensively include the findings “attributed Ziwiye” and “came from excavation”. However, many articles have been published about Zavieh’s findings, but parts of this collection still remain unknown and do not receive enough attention. The corpus of bone arrowheads is one of them, some of which were found during archaeological excavations while others came to museums from antiquities dealers. These include: the Metropolitan Museum of Art in New York, Musée du Louvre in Paris, the National Museum of Iran in Tehran, and the Sanandaj Archaeological Museum. This article aims to introduce and categorize 51 bone arrowheads. Some of these were registered as ivories, but our research concluded that all of these were made of bone. In few instances, the production manner prevented the proper identification of bone versus ivory. Another examined point in this research is whether such arrowheads were produced for actual warfare or for prestige and symbolic use in ceremonial events considering their bone material. The examined samples from other sites show that bone can be hard enough to penetrate game and human body even with light protection such as archery. Bone for making arrowheads was used for hunting big games and some tribes still use them.
