30 VIOLA 'Г. DOBOSI Group III: among the Upper Palaeolithical types the finest ones are the sidescrapers and the burins; especially the borers are atypical implements of an uncertain working. Group IV : the natural pebble splits lacking further working, as sectors whose backs are made by the pebble crust and whose edges need no retouching —especially if they are made of quartzite —can be counted among these. Group V : the reservations are mentioned above. The characteristics summarized by Bordes in a part of types 45-53 are regarded by Vértes 5 3—coding the finds of the Vértesszőlős Lower Palaeolithic site to a two-rowed punch card —as categories technologically separate, independent from the types, resp. to be connected with either of the implement groups. Group VI : It is questionable whether we have the right to call the implements of 3 to 4 cm clets or even "faustkeilartige" implements. Though the working on both sides, on places spreading over the whole surface, with a zig-zag-lined edge,, is characteristical, it is certain that they could not have a classical elet function. The same is valid for the pic, which is rather a pyramid sparsely retouched on its edges and a part of the not retouched points can be counted to the group of the geometrically broken pebbles. The bifacial quartzite implement (Fig. 10), collected by I. Skoflek, throws a new light on the possible connections of the Tata industry. 5 4 The implement material (Figs. 11-13) added to our collection from TataPorhanyóbánya through the Skoflek bequest and the revision of the chip material collected by Vértes does not alter the picture drawn by their specialists, it merely modifies and colours it bringing us maybe a step nearer to a fuller cognition. 5 3 Vértes, L., Typology of the Buda industry, a pebble-tool industry from the Hungarian Lower Paleolithic. Quaternaria 7(1965) 185—195. 5 4 After the archaeological excavation there was no limestone exploiting in the Porhanyóbánya of Tata. With the protection of the Tata lake-shore, the building operations in the environment of the high school and the constructing of the enclosure around the mine yard further basins might have been disturbed. A part of the finds from the Skoflek bequest was presumably found at these "outside" findplaces.
