ABSTRACT

Aim: To report the first ever made discovery of two 70,000 years- old prehistoric fossil sacra along with their detailed comparative morphometric study with modern human sacra to see any pattern of difference between the modern and prehistoric sacra.

Methods: In all 22 parameters were used for the metric analysis of the two fossil sacra which include 17 linear and curved measurements and five indices, and six were used as sexing criteria. These were compared with those of the extant Indian populations.

Results:  The two fossil sacra show some morphological difference from the modern human sacra in having less posterior curvature, and squarer outline of the male and rectangular of the female sacrum. They also exhibit very distinct sexual dimorphism in sacral index, though metric variables are within modern human range.

Conclusion: There are noticeable differences between the fossil sacra and typical modern human sacra, more so among the sexes indicating as if early humans were highly dimorphic sexually since ca.70-80 kya.

KEY WORDS: Fossil Sacra, morphometric comparison, Sacral Index, sexual dimorphism, Narmada valley.
