Evidence of cranial trauma was investigated in a skeletal sample from the site CA‐Ala‐329 located on the eastern side of San Francisco Bay, Central California. The sample included 365 crania, including 134 adult males, 104 adult females, 22 adults of indeterminate sex and 105 subadults. Evidence of cranio‐facial fracture was found in eight individuals, one of whom is an adolescent. Thus, the frequency in adult crania of traumatic injury is 7/260 (2.7 per cent). Of the seven individuals of known sex displaying such cranial trauma, all are male. The injuries are generally suggestive of some form of interpersonal aggression, with five healed vault fractures, one lesion with an embedded obsidian fragment (a probable projectile point) and two healed facial fractures. Further clear evidence of interpersonal aggression has been previously determined in this sample and has been reported at even higher levels elsewhere in California. © 1997 by John Wiley & Sons, Ltd.
