FIGURE 10.16 Proconsul africanus, maxilla. Photo, D. L. France; cast from National Museums of Kenya FIGURE 10.17 Proconsul africanus, mandible. Photo, D. L. France; cast from National Museums of Kenya 4. Compare the upper and lower jaws of Proconsul africanus (see Figures 10.16 and 10.17) to an extant chimpanzee mandible (Figure 10.18). Make a list of the dental similarities of the two forms. FIGURE 10.20 Chimpanzee (left), Sivapithecus indicus (center), orangutan (right). 6. Compare the face of Sivapithecus sivalensis (= indicus) (GSP15000) (see Figure 10.20) with an orangutan cranium. What are some of the similarities between this eight-million-year-old fossil face and the face of the extant orangutan?

What to look for on each skull Dentition Facial Morphology Cranial Morphology Shape of dental arcade, size of molars and premolars, size and shape of incisors, size of canines, jaw size Supraorbital torus (yes or no), prognathism (yes or no), canine fossa (yes or no), size of face, chin (yes or no), size of mandible, size and shape of brow ridges, nasal aperture size Sagittal keel brain size, vault shape, occipital torus, cranial capacity/size of brain, frontal bone shape Specimen name and number Gracile (G) or Robust (R) Facial Morphology (include dentition) Cranial Morphology 1. OH 5 Paranthropus boisei (R) Robust Austalopith Paranthropus boisei have a u shaped and a rounder dental arcade. 2. AL 288-1 Austalopithecus afarensis (G) Gracile Austalopith Australopithicus afarensis have a more v shaped dental arcade. 3. Modern Humans Homo sapiens (G) Gracile Humans have a v shaped dental arcade which is more angular in shape.
