Radiovisiography in Bone Density Analysis: the Supraorbital Region in Neanderthals and Early Modern Humans Versus that from Croatia

This study has given a new perspective on the comparative structure of the supraorbital region of fossil specimens (Vindija sample - Late Neandertals, Velika pećina sample - Early Modern Homo sapiens) compared with recent specimens. The method used was digitalized radiovisiography, which provided a pseudocoloured bone structure survey in both two- and three dimensions, along with bone density coefficients for each cross section (the maximum level as high as 256 - the level of the metal density used in implantology). Seven fossil supraorbital tori were x-rayed (6 from Vindija and a single one fragment of Early Modern Homo sapiens from Velika pećina). A comparison was carried out on the total of 20 recent supraorbital parts (left and right). These were compared with 20 recent supraorbital parts (left and right). Three vertical sections of each supraorbital were taken by radiovisiography. Within the taxon of Homo sapiens neanderthalensis the highest bone density values obtained varied according to sex, age at death as well as layers of the complex G3 from which they were excavated. The highest bone density value for the Early Modern Homo sapiens was observed in the region of the so-called supraciliary triangle. In the recent sample, both sexes showed a tendency for highest bone density in the lateral section of the supraciliary arch.
