Ubicado en un extraño paisaje lunar de gran interés geológico, el sitio de Tasili n’Ajer alberga uno de los conjuntos más importantes del mundo de arte rupestre prehistórico. Unos 15.000 dibujos y grabados permiten seguir las huellas de los cambios climáticos, las migraciones de la fauna y la evolución de la vida humana en los confines del Sahara, desde el año 6000 a.C. hasta los primeros siglos nuestra era. Las formaciones geológicas en forma de “bosques rocosos” de arenisca erosionada revisten un ...

Located in a strange lunar landscape of great geological interest, this site has one of the most important groupings of prehistoric cave art in the world. More than 15,000 drawings and engravings record the climatic changes, the animal migrations and the evolution of human life on the edge of the Sahara from 6000 BC to the first centuries of the present era. The geological formations are of outstanding scenic interest, with eroded sandstones forming ‘forests of rock’...

Clovis Technology


A new book on the stone and bone tool technologies of Clovis culture of 13,500 years ago, published by faculty at Texas State University, is the first complete examination of the tools themselves and how the Clovis culture used them and transmitted their production.

The book, “Clovis Technology (International Monographs in Prehistory, Archaeological Series 17),” covers the Clovis culture's making and use of stone blades, bi-faces and small tools as well as artifacts such as projectile points, rods, daggers, awls, needles, handles, hooks and ornaments made from bone, ivory, antler and teeth.

It examines the tools used to make other tools, such as billets, wrenches, gravers and anvils, and explores how Clovis culture acquired and transmitted stone tool production.

It is co-authored by Texas State archaeologist Michael B. Collins, who also directs the renowned Gault archaeological site in Central Texas, the world's largest Clovis excavation.

It is estimated that more than 60 percent of known Clovis artifacts have come from the Gault site near Florence. Until recently, Clovis technology was believed to represent the Americas' earliest human inhabitants, having arrived in the hemisphere from Asia by walking across the Bering Land Bridge between 11,000 B.C. and 8,000 B.C.

However, recent discoveries at Gault and elsewhere, of stone and bone artifacts predating Clovis, have convinced most archaeologists that a culture existed in the Americas at least 500 to 1,000 years before Clovis, possibly arriving by boat and on foot.

“Our book, the first thorough examination of Clovis technology, is a step towards determining what came before Clovis,” Clark Wernecke, executive director of the Gault School of Archaeological Research, said.

“By starting with what we know, we can look for indications of what came before.”

Book co-authors include Bruce A. Bradley, director of the Experimental Archaeology Master's Programme at the University of Exeter, and C. Andrew Hemmings, Mercyhurst College.

Contributors include Jon C. Lohse, director of Texas State's Center for Archaeological Studies and Marilyn Shoberg, Texas Archeological Research Laboratory.

El Dolmen de Azután (Azután, Toledo, España) fue la primera de las evidencias megalíticas localizadas en el interior de la Meseta Sur con fechas radiocarbónicas que permitieron situar cronológica y culturalmente las poblaciones del Neolítico medio, final y Calcolítico en la cuenca media del río Tajo y sus relaciones con el abundante fenómeno del Megalitismo del interior peninsular...
