This skull exhibits large supraorbital height index of approximately71 uv/tv. This almost matches the supraorbital size of Australopithecus africanus skull and Neanderthal skulls that are 70uv/tv and 70uv/tv respectively. An analysis on the nuchal ridge area was also taken it had a height of 39tw/tv. A comparison was then drawn with regard to the known varieties; there was closeness with the nuchal skull of Australopithecus africanus and Neanderthal that had a nuchal area of 38tw/tv and 37tw/tv respectively. A further measurement was done on the condylar position on the skull. It was found out that the condylar position index was 44xy/xz. When this was compared with known varieties of skulls; there was an exact match with the condylar index of Australopithecus africanus that was also 44xy/xz.
To ascertain the identity of this skull, a further analysis was done and the physical characteristics of the skull and different traits were observed. The canine teeth were relatively smaller and the shape of the jaw was fully parabolic. These characteristic were shared with the skull of Australopithecus africanus. In general, this skull is possibly a skull of Australopithecus africanus
The results revealed that the supraorbital height index of this skull is 66uv/tv which was relatively smaller compared to the first skull (Elbroch, 2006). Although, this exactly matches supraorbital size of Homo sapiens skull that is also 66uv/tv. Another study on the nuchal area height was also conducted and gave a height of 18tw/tv. It was observed that it was also smaller in size compared to that of the first skull but was closer to that of Australopithecus robustus. A ...Download file to see next pagesRead More

Wheel of Fortune and Invocation by Flack
...Painting Analysis: Compare and Contrast Audrey Flack is an internationally recognized artist out of New York who pioneered photorealist painting. Although she approaches her work with a fascination for the surface illusion, she does so with a unique collage-style approach in works such as Wheel of Fortune (1977-78) and Invocation (1982). Both Wheel of Fortune, a 96 inch square oil on acrylic, and Invocation, 64 x 80 inches also oil on acrylic, are classified as vanitas paintings which explore the brevity of life. Both pieces feature an unrealistic collage of still life items, including a realistic human skull. The items included in these still lifes are not unrealistic in their depiction, but rather in their placement. Wheel... of...

In most of the cases, it is done to reshape the existing shape of the face. Craniofacial reconstruction is performed to reshape either the skull or the face of the patient. In this procedure, the upper part of the skull is restructured and due to this it is known as craniofacial.

Mystery Skull
...Mystery SkullSkull identification entails the observation of the index traits and the non-index (physical) traits. First we can start by referring to the index traits of the mystery skull #1 to make a comparison with the traits of the skulls given in chart 1. These index characteristics are; 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 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...

Ontogenetic change in skull morphology and Mechanical Advantage in the Spotted Hyena (Crocutacrocuta)
...The Ontogenetic Change in the Skull of Hyena (Crocuta crocuta) Animals require food for growth and survival. However, it depends on how well they are adapted to obtaining and processing food materials. For mammals, the young ones feed on milk from their mothers before weaning period when they are introduced to an adult diet. Hyenas are carnivorous, and weaning is associated with functional challenges due to violent competition in feeding. Spotted hyenas (Crocuta crocuta) used in the study must overcome extreme conditions of intense feeding competition and crack of bones (Holekamp, Lundrigan, Tanner and Zelditch 354). Adult spotted hyena have durophagy adaptations that include large jaw, adductor muscles, simplified and...

...and Trinil 2. In 1891, an archeologist named Eugene Dubois found angular, domed, and thick-walled human skullcap with a large shelf like brow ridge near Trinil, Java (Indonesia. He decided that the skull be named Trinil2 (Dorey). Another person, Kamoya Kimeu in 1974 discovered a 1.7 million years old femur of Homo erectus KNM-ER1808 in Koobi Fora in Kenya. This female Homo erectus has an incredible distinct feature that surprised the researchers; it has an abnormal layer of bone on her thigh that shows evidence of bleeding to her death. Scientists have concluded that it is an overdose of vitamin A. The two skulls have some significant differences between them. Trinil 2 has a long, flat forehead, distinct...

Skull
...Identifying Skulls Introduction Many changes that have occurred in hominid evolution have been the change in proportion of the skull. Skull proportions show the different parts of the skull. The changes are noticeable when the two hominid trends: brain versus face size and the position of the occipital condyles, are measured. In this task, we are going to measure different lengths of the skull and calculate the skull indices and then compare the calculated value with some known recognized hominin species. Theory The main parts of the skull are the porion, occipital condyles, prosthion and the inion. The porion is the...
