Abstract
In 2009 morphological study of dental crown measurements were made on 162 individuals of the Shiqiao site in Tainan, Taiwan which dated to Niaosong phase of the Niaosung Culture (1200~1500B.P.). The evidence comparing the genetic homogeneity of males versus females suggests a post-marital residential pattern for Shiqiao site that might not be simply either matrilocal or patrilocal. Rather, the best explanation is a bilocal residential pattern with a patrilocal bias. Analysis of (87)Sr/(86)Sr isotopic ratio is expected to approximate the same result. Sr isotopic analysis of twelve individuals revealed significant differences in sex and age cohort. Male individuals are more homogeneous than female. In the meanwhile, subadults are homogeneous and closer to male individuals. This result matched the bilocal residential pattern with a patrilocal bias model which built by dental crown measurements. But, this research is still controversial that may be due to the small sample size and local range of Sr isotopes has yet to be established. We are expecting to accumulate more strontium isotope data to concrete the inference in this study.
