RESUMEN
This study examined forty skull samples of ancient children, aged 2-15 years, excavated from the Zaghunluq cemetery in Xinjiang, China. The purpose of the study was to analyze the patterns of age-related physiological development and growth spurts in the skulls of these ancient children by comparing the projected areas of the bottom view of the skull, the occipital bone, and the maxilla among different age groups. The analysis of variance (ANOVA) revealed significant differences in the projected areas of the skull's bottom view, occipital bone, and maxilla among five age groups (2 years old, 3-5 years old, 6-8 years old, 9-11 years old, and 12-15 years old). The growth spurts in the projected area of the occipital bone occurred at ages 3-5 years and 6-8 years. As for the maxilla, the growth spurts took place at ages 6-8 years and 12-15 years. Meanwhile, the projected area of the skull's bottom view exhibited a continuous increase without any periods of rapid growth. These findings may reflect the patterns of age-related growth in the skulls of ancient children in Xinjiang, China.
