Neandertals take out their small blades

Excavations of Neandertal artifacts at two caves in northern Spain have yielded an unexpected discovery—a trove of thin, double-edged stone blades that researchers usually regard as the work of Stone Age people who lived much later.

In 2005, Federico Bernaldo de Quiros of the University of Léon in Spain and his coworkers unearthed small stone blades, which they called bladelets, lying amid larger, characteristic Neandertal stone implements in a cave called El Castillo.
