Mylohyoid and jugular foramen bridging in pre‐columbian chileans
Abstract The occurrence of mylohyoid groove bridging and jugular foramen bridging was determined in a population of adult Pre‐Columbian Chileans. Two hundred forty‐one crania (110 males, 131 females) were examined for jugular foramen bridging and 464 mandibles (252 males and 212 females) were observ...
