Anasazi pueblos in States). Breakage of the zygomatic arches is necessary in order to remove the temporalis muscle so as to open the vault for access to the brain tissues. Other animal maxillae are heavily broken, with only alveolar fragments and few premolar and molar preserved in situ. Horses show percussion marks on buccal and lingual sides, or only on the buccal. Cut-marks have not been seen on the bone of horse maxillae, but there are two specimens that show oblique cuts on the buccal side of the premolar/molar toothrow (Figs 2IB, 22). Extensive percus- sion marks appear on both the lingual and the buccal sides of horse maxillae, and one specimen has adhered flakes also on both sides. It is interesting to note that one horse maxilla has peeling on the Fig. 17 Innominate of Equusferus M50028. This bone has been extensively modified, with loss of the extremities and many trampling marks on both surfaces. There are many carnivore tooth marks on the upper border of the ilium, and four chop marks are also present crossing the spine near the superior border of the ilium. More inferiorly there are numerous cut-mark incisions concentrated along the spine; x With regard to cervids there are cuts only on the buccal side of the maxilla, along the dental series (Fig. 21C). Percussion marks on the lingual side have
