Eieven samples from Upper Paleolithic layers of karst cave Bondi have been investigated by the method of palynological analysis. The pollen and spore content there turned out to be very scarce, however, non-pollen fossils (=non-pollen palynomorphs) were represented better. In the lower layers many flax and wool fibers were found. High quantities of flax fibers and especially the presence of tWisted and painted fibers in the Bondi cave layers indicates the hand-made production of textile. In the Upper Paleolithic mixing of wool and flax fibers had already been used to make the knitted fabric durability, i.e. the knitting technology were being improved. The cave Bondi was used by man in the periods of cooler climate which were three for the time of sedimentation of the studied earth stratum. The maximum quantity of flax fibers together with the pollen of cold-loving plants can be used as an indicator of coolings. Their minimum contairi,on the contrary, indicates climate warrnings. This point is important when pollen is absent or when pollen spectra are poor. Investigation of a group of non-pollen palynomorphs (NPP) in the archaeological material is very promising for solution of many problems of culture history of ancient
