Early paleozoic era
An aerial view of the sediments that accumulated in the shallow ocean that covered much of southeastern Minnesota and adjacent areas in the early Paleozoic Era. Compare to Figure 4 and note how changes in sea level result in a shifting of the kinds of sedimentary particles that are deposited (from Mossler, 2000, MGS Rept. of Inv. 50).The temperature of a planet is linked with the diversity of life that it can support.
