The Pilsen-Senec Mesolithic station is situated on the left banks of the Berounka River, 14-16 meters above its current level, in an industinct saddle 326 m above sea level. The chipped stone industry form Pilse-Senec has a distinctly diverse material composition. The raw material are predominantly local and include different varieties of hornstone, lydite, slate, quartz, sandstone and limonite. Imported materials are represented by Nordic flint, differnet varieties of Bavarian hornstone and northwest Bohemian quartzite (Bečov, Skršín and Tušimeice types). The cipped stone industry from Pilsen-Senec is a relatively large collection of artifacts (2 069 pieces) with madny different raw materials. Trhe pridution part of the collection is absolutely predominat. The number of microliths and retouched artifats is very small. Hammerstones,anvils and heating stones are also presnet. Covetional typological analysis has differentiated between two groups of artifacts. The first group has characteristic Mesolithic microliths - such as Komornica type points, sements, a triangle, Borki type blade, and microblades. A tendecy toward microlithization is also indicated by several other tools such as end-scrapers, burins and awls. The second group consists of artifacts typical for the late Paleolithic period, for example a convexed backed point, chisels, awls,, bacek blades, lateral burigns and long blades. Using the typical approach, it would seem appropriate to divide the complex itno twoo cultural complexes- late Paleolithic and Mesolithic., Jan Fridrich, Ivana Fridrichová-Sýkorová, Milan Metlička., and Obsahuje seznam literatury
