Document Summary
Requires more calories for quadrupeds going long distances. Majority of fossils found in east and south africa. Most fossils in east africa are in a rift valley. South africa has a lot of limestone and the limestone erode to form subterrainian caverns. Organisms are brought in and fossilize in breccia. Breccia- very hard, cement like matrix of pebbles, soil and sand that encases fossils. More difficult to date fossils in south africa because little/no volcanic activity. Post orbital constriction, poc narrowing behind the eye orbits. Supra-orbital torus, sot- enlarged area of one above the eye orbits, aka brow ridge. Sagittal crest- sharp ridge of bone that runs down the center of the skull, for muscle attachment. Nuchal crest- crest in the back of the skull that runs horizontally. Spoiler- fossil/ artifact that messes up the traditional fossil record. The more fossils that are found, the less is understood.
