At the time of the of the epigravettian occupation around 17,000 years ago, the whole region was a cold steppe with pine, juniper and occasional clumps of cold resistant shrubs. The cave sites of central Bosnia contained bone assemblages indicating that a variety of animal species occupied the mountain regions. The steppe was probably the domain of large herbivores.
Rows of bison teeth reduced to the enamel were the only faunal remains recovered at Kadar. Two were found in I West neqar the hearth along with small fragments of burnt bone. And three were recovered in Unit A, Kadar II.
Stone Age hunters probably camped on the Kadar hilltop to survey the wide plains of the Sava River and its tributary, the Bosna waiting for the passage of bison herds.
