Document Summary
Biostratigraphy: analysis of the earth"s stratified layers to uncover evidence based from fossils. Principle of superposition: rock layer at the bottom of the pile will be the oldest; top layer = youngest. Principle of faunal succession: strata of like age can be recognized by fossils they contain even if they are separated by a large distance: (faunal means animals and plants of a particular region) Phanerozoic emergence of creatures with hard parts. Base of periods defined on emergence or radiation of new species. Base of mesozoic and cenozoic emergence of new species following mass extinction. Change in continent configuration: climate, ocean cyclinity, sea level weather patterns, greater the landmass = lower the diversity. Changes in the atmosphere: greenhouse warming and shit. Sea floor spreading slowed down: sea level dropped fucked over shallow habitats. Climate got drier and more drought because of large landmass. Siberian traps: lot of volcanic activity acid rain.
