The site was discovered and investigated between 1977 and 1985. Assemblage includes c. 6000 lithics. The technological analysis allowed to elucidate highly complex system of different core reduction strategies, which were applied at the site. The overwhelming majority of knapped products were obtained through the exploitation of flat cores, although the idea of volume was also known and time to time was applied. Three specific forms of pre-cores can be distinguished, each of which adds specificity to modes of further reduction: careful curation of pre-cores by removal by different methods of preparation of striking platform zone (trimming, faceting) and of maintaining of flaking surface convexity (different debordants) was conducted during each stage of core reduction. There is evidence of a variety of recurrent methods, frequently regarded as Levallois, namely centripetal, uni- and bipolar, corner etc. Classical Levallois technique oriented to obtainment of a single removal through pre-core-one cycle is also represented. “Ideal blank” approach allows to define the desirable blank as bladey flake/short blade of Levallois appearance. The most specific features of Provadnyi technology are consist in frequent application of trimming technique during striking platform preparation and in acquaintance with volumetric mode of raw materials exploitation, resulted, among other, in particular type of pre-cores. mar., 12 mai 2026 11:32:44 +0200 https://popups.uliege.be/3041-5535/index.php?id=471 https://popups.uliege.be/3041-5535/index.php?id=478 mar., 12 mai 2026 11:33:02 +0200 https://popups.uliege.be/3041-5535/index.php?id=478 https://popups.uliege.be/3041-5535/index.php?id=480 The proposed reconstructions of Aurignacian split based points production and hafting are based on the use of mechanical properties of wet deer antler – bending strength, elasticity and longitudinal fibrous. The efficient production of split is possible with two reliable methods (or so-called “split drive technology”) when the final reception of “tongued piece” and only snapped fragments are available. Both methods are based on the gentle bending of antler blank in the place of transversal slot which is carried out with “baton forces” or even fingers. The additional control of direction and spread of crack through body of antler is possible with some kinds of wedge-like lever (first of all pre-part of wood shaft, special antler chisels and wedges or even other tongued pieces). The reconstructed method of hafting is attached with above-mentioned technology of their production. The flat wedge-shaped wood foreshaft of projectile is driven in split base point between the wet “wires”. The latter is bound over wet sinew which efficiently fixed point on the shaft just after leary or drying. Perhaps, the sinew also was used for fixing of Aurignacian microliths on the surface of antler point in flat position as scale-like barbs. The proposed hypothesis also explains some archaeological data both unfinished or damaged points and different wastes of points production from archaeological assemblages. mar., 12 mai 2026 11:33:21 +0200 https://popups.uliege.be/3041-5535/index.php?id=480 https://popups.uliege.be/3041-5535/index.php?id=484 mar., 12 mai 2026 11:33:42 +0200 https://popups.uliege.be/3041-5535/index.php?id=484 https://popups.uliege.be/3041-5535/index.php?id=486 mar., 12 mai 2026 11:34:05 +0200 https://popups.uliege.be/3041-5535/index.php?id=486 https://popups.uliege.be/3041-5535/index.php?id=488 La fréquence relativement importante d’os brûlés dans certains gisements préhistoriques pose le problème de leur origine. Ils ont pu être brûlés en cours de cuisson, utilisés comme combustible, jetés dans le feu à des fins d’hygiène ou bien encore brûlés accidentellement (enfouis sous l’emplacement d’un foyer ou brûlés par l’action de feux naturels). Certains points ont déjà été vérifiés expérimentalement, cependant, l’emploi de l’os en tant que combustible et les implications taphonomiques qui en découlent sont des sujets rarement abordés. Cet article préliminaire fait suite à une série de dix expériences réalisée à partir d’os frais de mouton afin de mettre en évidence les potentialités de combustion des os en fonction de leur nature histologique et de leur degré de fragmentation. Il sert de préambule à une réflexion plus générale concernant la taphonomie des os brûlés. Les résultats préliminaires obtenus montrent que l’os peut effectivement servir de combustible : seuls les os frais participent à la combustion ; les os secs consomment moins n’apportant aucune énergie au foyer. Les os non consommés ou les parties spongieuses sont de bons combustibles en revanche les fragments de diaphyse seuls brûlent mal. La fracturation intentionnelle des parties spongieuses favorise la libération de la graisse et facilite donc la combustion. Un feu ne peut pas être démarré avec des ossements ; il doit, au préalable, être amorcé avec d’autres types de combustibles produisant une température suffisamment élevée pour permettre l’inflammation de la graisse osseuse. En revanche, à condition que la température ne baisse pas trop, un foyer peut être ensuite alimenté uniquement avec du combustible osseux. Burnt bones are common in some prehistoric sites. Their presence can result from a variety of processes. These include natural fires sweeping across land surfaces, the accidental burning of food, the use of fires for refuse disposal, or the intentional use of bones as fuel. Although some archaeological experiments have been conducted on burnt bone, more work is required on the use of bones as fuel. Our experiments, based on sheep bones, lead us to conclude that bones can be used as fuel, but some skeletal elements make better fuel than others. Only bones that contain grease participate in combustion. Dry bones were carbonized but contributed little energy to the fire. Complete long bones or cancellous portions make good fuel. This contrasts with long bone shaft fragments that burned badly because of their low grease content. Intentional fragmentation of cancellous portions of bones helped to release their grease. This enhanced their ignition and combustion. It was impossible to ignite a fire using bones as tinder. Other materials must be used to ignite the fire. Once a critical temperature was reached bones could be added to sustain the fire, because the liquefied grease became flammable. A fire may be sustained using bones only if the temperature is not allowed to drop below the critical temperature threshold. mar., 12 mai 2026 11:34:26 +0200 https://popups.uliege.be/3041-5535/index.php?id=488 https://popups.uliege.be/3041-5535/index.php?id=505 mar., 12 mai 2026 11:34:50 +0200 https://popups.uliege.be/3041-5535/index.php?id=505 https://popups.uliege.be/3041-5535/index.php?id=507 mar., 12 mai 2026 11:35:07 +0200 https://popups.uliege.be/3041-5535/index.php?id=507 https://popups.uliege.be/3041-5535/index.php?id=509 mar., 12 mai 2026 11:35:23 +0200 https://popups.uliege.be/3041-5535/index.php?id=509
