Cambrian Paleogeography: Shifting Seas and Transformative Geology, Slides of Earth Sciences
The geological history of the cambrian period, focusing on the transgressions and regressions of shallow epicontinental seas that covered the central us. The impact of proterozoic glaciations on sea levels, the visible evidence of these changes in the grand canyon, and the variable sea levels represented by sequences of sediments on cratons. Additionally, it covers the ordovician period, early paleozoic climates, and the emergence of diverse life forms during the cambrian and ordovician eras.
