Biological identification of an individual is the most important aspect in terms of forensic investigation, disasters, natural calamities, etc. Moreover the sex determination is the difficult task in many situations of body remains obtained from such cases. Among the most reliable criteria for gender identification, pelvimetry serves to be the first preferred choice in many cases. As far as the pelvic bone is concerned, many morphological and morphometrical bony features serve as an important tool in gender identification. In the present study we analysed the greater and lesser sciatic notch of pelvic bone for observations of any sexual dimorphic characters. The aim of the study is to evaluate the morphological and morphometrical analysis of greater and lesser sciatic notch for sexual dimorphism in pelvic bones in SDC. A total of 50 bone samples were used from SDC. Vernier calliper was used to measure the bones and results were analysed and tabulated. From this study, we can debut that, indices of the greater sciatic notch are known to be highly sexually dimorphic. The pelvic girdle has always gathered importance, in anthropometry especially due to the sex differences between greater sciatic notches of the two. Further studies should be conducted for a better understanding of the morphology of pelvic bones in the Indian subcontinent.
