Zbirka 134 orinjasjenskih koščenih konic z masivno bazo iz Potočke zijalke je po 90 letih od odkritja še vedno največja takšna zbirka v Evropi. Konice, ki so bile večkrat predmet različnih ...raziskav, so bile najdene v dveh plasteh na dveh lokacijah z različnim bivalnim in sedimentacijskim mikrookoljem. Glede na vzdolžni presek konic sta z velikim številom primerkov v obeh plasteh in na obeh lokacijah zastopana dva različna tipa konic: ploščat in vretenast, ki se razlikujeta tudi po tehničnih lastnostih. S po enim primerkom je zastopanih nekaj monotipov, med katerimi je tudi t. i. tip mladečke konice. Sto sedemnajst konic obeh glavnih tipov je tokrat prvič sistematično analiziranih z uporabo standardnih parametričnih in neparametričnih statističnih postopkov na podlagi kombinacij 20 znakov: 9 metričnih in 11 opisnih. Glede na izsledke analiz je predlagana vrsta novosti o domnevnih razvojno-tehničnih izboljšavah konic, načinu nasaditve, popravilu poškodb, izdelavi nastavkov za večje konice in pomenu zarez na robovih nekaterih konic. Avtorja ugotavljata, da gre pri tipu vretenastih konic Potočke zijalke za tehnično izpopolnjeno obliko konice z masivno bazo, ki si upravičeno zasluži naziv konica Potočka zijalka ali olševska konica.
Archaeological finds indicate the use of bows and arrows in the Palaeolithic, though there is no consensus among archaeologists as to its beginnings. The main reason for this lies in the perishable ...materials used to make archery equipment. Among the finds that could offer indirect evidence for the use of bows in the Palaeolithic are small stone and bone points. Of the latter, the small bone points found in the cave of Potočka zijalka, Slovenia, led to a reconsideration of the existence of archery and archery equipment in the Aurignacian. The cave revealed 125 well preserved bone points, six of which were established to be roughly 32 ky old using the AMS 14C radiometric method.
At one of the most important Aurignacian sites in Europe, the cave of Potočka zijalka, part of a bladelet of the Dufour type was recently discovered. It was lying on the surface ...of the heap of sediments excavated by Srečko Brodar in the years 1928–1929 in the rear of the cave. Potočka zijalka is known primarily for the 125 bone points and 11 other bone tools found there in a perfect state of preservation and bearing the age of approximately 30,000 years. It is interesting to note that almost contemporaneously with the appearance and use of the bone points from Potočka zijalka, the nearby cave site of Vindija in Croatia was used by the Neanderthals, the bone remains of which were uncovered in the youngest Mousterian G1 complex of Vindija together with bone points
