In-depth study of Acheulian limestone artifacts from Gesher Benot Yaʻaqov (0.79 Ma) has revealed that limestone nodules procured from fluvial deposits were transported to the lake margin and exploited throughout the occupational sequence (ca. 50 ka). Analyses of the limestone assemblages show that individual artifacts went through several use-stages or complex life-histories within a single reduction sequence. This reduction sequence began with the targeting of nodules suitable for use as percussors. Use of the percussors sometimes resulted in breakage that produced flakes typical of working accidents. Broken percussors were shaped into a second morphotype, chopping tools, while cores comprise a third morphotype. These morphotypes are viewed as consecutive, interrelated options. Once a morphotype was inadequate for use it was transformed into another, resulting in gradual reduction of dimensions from one type to the next. The ability to renovate/recycle implies flexibility and contingency.
