ABSTRACT
Determination of deceased sex is first step in skeletal analysis since estimation of age, race, and stature depends on sex of deceased. Total 100 adult human skulls (50 male and 50 female) of Hyderabad-Karnataka region are studied. Measurements like foramena magnum length and foramena magnum breadth were measured. The demarking point (D.P.) and identification point (I.P.) of both measurements was calculated and then percentage of bones identified by D.P. and I.P. was recorded. Though, the Demarking Point of a single parameter may not identify sex in all the bones but the accuracy is nearly 100% in the bones, which are identified. Percentage of skulls identified by IP and DP of foramena magnum length is more as compared to foramena magnum breadth. So foramena magnum length gives better prediction of sex as compared to foramena magnum breadth.

INTRODUCTION
Several forensic anthropologists have described qualitative sex differentiation using many bones, but sexing from single bone is difficult task. Almost all the elements of human skeleton show some degree of sexual dimorphism, but reliable indicators can be obtained from specific bones like hip bone, skull and sacrum. The determination of deceased sex is first step in skeletal analysis since estimation of age at death, race, and stature depends on sex of deceased.
The measurements of the skeleton bones, mainly the neurocranium (brain case) and viscerocranium, suffer influences of various factors; however, they are often used for human population morphological studies of age estimation, stature, ethnicity, which are relevant aspects of forensics investigation and anthropological examinations of unknown individuals1.
Recent studies report that morphometry is a fast and efficient method for the evaluation of morphological characteristics, such as ethnicity, gender, age, genetic factors, dietary habits, and regional variations which can alter the shape and size of bone structures. These aspects are significantly important in determining the anthropometric changes between different populations and genders2
Traditional method is non-metrical and morphological. Morphological features of bones depend upon nutrition, occupation, race and geography of the region, so the traditional method is not reliable in the study of bones.
In this study length and breadth of foramena magnum were studied. They were analysed statistically by applying...
