The last fifteen years the Archaeological Service of Florina has conducted extensive surface surveys and large scale excavations in the Prefecture of Florina that changed dramatically our knowledge about the prehistory of this part of Western Macedonia.

Most of the excavations where held in the coal mining zone of the Public Power Corporation near to the lakes Chimaditis and Zazari. According to recent data, between the four lakes of the area (Lake Chimaditis, Lake ZazariLake Vegoritida and Lake Petron) a lot of prehistoric settlements were established that date back to Greek Early Neolithic (6700/6500-5800/5600 BC) to Late Bronze Age (1700/1500-1100 BC).

It seems that many of the settlements, that were established in the northern shore of the lake Chimaditis and near to the lake Zazari, were wetland settlements. One of the most important lakeside settlement that is still being excavated is the Anarghiri IXb settlement located near to the modern village of Anarghiri. The investigation so far yielded thousands of wooden piles that were used in house infrastructure, wooden structures that can be characterized as bridges or pathways inside the lake, a lot of thermal structures and thousands of figurines, chipped stone tools and osseous artifacts.

So far there were almost 500 antler artifacts, making this assemblage the biggest worked antler assemblage in prehistoric Greece. Their study showed the presence of semi products, completely manufactured items and waste. The assemblage is characterized by a great variability as so far there have been found picks, bevel ended tools, intermediate tools, axes, projectile points, harpoons, maceheads, shaft straightners, ornaments and figurines.

In this short presentation there will be an attempt to present the preliminary results of the ongoing study of the antler artifacts, that is related with their manufacture, the typology, the raw material preferences and use.
