ered a sex-related trait in other populations (ERY 1990/?). Numeric variability within particular segments of the vertebral column, especially in the lumbar and sacral sections, is often evened out between sections: when six lumbar vertebra are counted, the sacrum often consists of four segments or vice versa. However, the sacralization of the caudal vertebrae plays no role in this process. In addition to the previously mentioned anomalies, the presence of cervical ribs is worth mentioning in a woman (No. 71) and a man (No. 312) respectively. The 1 st and 2nd ribs of a woman (No. 424) were fused like those of two children (No. 373 and 47, Fig. 35). Sexual dimorphism The expression of sexual characterics in the Tác population is illustrated by data summarized in Table 5. The masculinity of males is strongly manifested on both the skull and the postcranial skeleton. Of the 22 traits listed here, the os zygomaticum (+1.18), the angulus mandibulae (+1.01) and the caput femoris (+1.24) appear to be most masculine in character. Masculinity is least expressed in the margo supraorbitale (+0.33) and on the sacrum (+0.32). The femininity of females is poorly manifested on the skull but better expressed on the postcranial skeleton. Of the 22 traits analyzed, angulus subpubicus (-1.09), cotylo-ischiadic index (-1.2) and caput femoris (-1.23) may be considered most feminine. The appearances of corpus mandibulae (+0.11), angulus mandibulae (+0.15) and linea aspera (+0.15) were found to be the least useful markers of femininity. Sexual dimoiphism in the Tác population is most expressed on the glabellar region (+0.83 / -0.81 ), on the angulus subpubicus (+0.87 / -1.09), on the incisura ischiadica major (+0.90 / - 0.78), on the ischio-pubis index (+0.81 / -0.94) and on the caput femoris (+1.24 / -1.23). Metric and morphological characteristics Individual cranial measurements and indices as well as postcranial skeletal dimensions for people over 18 are listed in Tables 17-18 and 19-20. Statistical parameters of the skull are summarized in Tables 6-7, and the distribution of cranial length-breadth index by categories is presented in Table 8. A list of morphological characteristics recorded on skulls is provided in Table 9. Statistical parameters for
