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) ...
