1830-8<BR> Discoidal stone; Los Muertos Compound XXII, , Civano phase, Hohokam Classic period; l. 10.7 cm.; A.D. 1150-1450.<BR> Discoidal stone with worked edge and polished base; "VVII 1694b" (in red), "1775b" (in black on top). According to Alan Ferg of the Arizona State Museum, this specimen is probably a one-handed mano-made-of-a-pebble, for use on a slab-metate. Bernard-Shaw (1983:399-400) has pointed out the variability in shape and use of manos found in Hohokam sites (cf. Haury 1976:281-282). Studies of food grinding stones from the prehistoric and historic Southwest and the Middle East have show that tool morphology is less associated with differences in wild and domesticated plant species that were processed. Instead, such variability is more closely related to differing processing strategies, such as the grinding of dried seeds and kernels into flour, fresh soaked kernels into masa, and oily seeds into paste (Adams 1993, 1999).<BR>
