THE EVIDENCE FOR NEANDERTHAL LITHIC TECHNOLOGY IS REVIEWED AND SUMMARIZED FOR FOUR CAVES ON THE ROCK OF GIBRALTAR: Vanguard, Beefsteak, Ibex and Gorham's. Some of the observed patterns in technology are statistically tested including raw material selection, platform preparation, and the use of formal and expedient technological schemas. The main parameters of technological variation are examine...

The study of the morphology of stone artifacts and their spatio-temporal changes in form has gained great importance in Paleolithic archaeology today. This growing attention is due to the prevalent use of advanced multivariate statistical methods in archaeology, the growing connection between archaeologists and the specialists of life sciences (e.g., animal biosystematics) and programming langu...

Introduction: The Rochechouart impact structure is a deeply eroded, late Triassic impact site located in south-central France [1,2]. Rochechouart impactites comprise five main lithological units from the base of the structure upwards, originally described as follows: unit 1) shocked autochthonous basement rock; unit 2) finely crystalline melt rock; unit 3) red 'welded' breccia/suevite; unit 4) ...

Introduction: We report Modified gaussian model (MGM) deconvolution analyses [2] of reflectance spectrum of the Yamato (Y) 981031. Petrological characteristics of Y981031 had already reported [1]. Absorption features derived from the MGM deconvo-lution are compared with the petrological characteristics of Y981031, and implication of the absorption features are discussed. Finally, we propose sou...

Marcel Otte recently argued (In "Comments on Mezmaiskaya, North Caucasus", Eurasian Prehistory, this issue) that the Early Upper Paleo-lithic (EUP) at Mezmaiskaya Cave can be defined as Aurignacian (versus Golovanova et al., 2006). This raises an old methodological problem concerning the correct use of scientific terms and the definition of the Aurignacian. Lithic definitions such as Aurignacia...
