Need an research paper on skull identification. Needs to be 5 pages. Please no plagiarism. There are three indexes normally used in the identification. index of the supra-orbital height (uv/tv), index of the index of nuchal area height (tw/tv) and the index of condylar position (xy/xz). The positions of t, u, v, w, x, y and z are shown on the various figures of the specimens given. The indexes of the nuchal area height and the condylar position utilize an area of a plane called the Frankfurt plane which is a line passing through the top of the ear opening from the bottom of the eye socket.
The index of supra-orbital height is a measure of the height of the skull that is above the eyes for the various skulls to be identified. Indirectly it is a representation of the cranial height and also a measure of the dimension and complexity of the cerebrum. To obtain this index the distances uv and tv are measured for the skulls to be identified and compared with the values for the known specimens.
The index of nuchal area height is a measure of the position and the height of the foramen magnum relatively in the skull. It enables the determination of the uprightness of the posture of a skull and thus of the fossil as the whole. It is determined by measuring the distances tw and tv and finding their ratio. These ratios for the fossil skulls to be identified are compared to the ratios of the known specimens during the identification. The index of the condylar position is a measure used to show how straight a hominid stood. It is used to determine the extent backwards or forwards to which the occipital condyles (projections arising from the bottom of skull connecting the skull to the neck) are. In the identification, the names of the specimens C, D, E, F, G, H and B are given in the chart and any reference made in this report should be counterchecked in the chart.
The mystery skull #1 has the values of the three indexes discussed above recorded as 65, 23 and 90 respectively. The skulls were first grouped with reference to the index of supra-orbital height and the specimens D, F, G, H, I and B whose scientific names are given in chart 1 were found to the potential identities of the mystery skull. . .
