The Paleozoic Era. . Geologic periods in Paleozoic record 7% of Earth's history Cambrian, Ordovician, Silurian, Devonian Carboniferous (Miss., Penn.) Permian Boundaries in the major divisions originally defined by changes in the fossil recordStart of the Paleozoic used to be defined by appearance of first easily visible fossils; later lowered to include small shelly fauna; then lowered further to first appearance of complex branching trace fossils. .

North America During the Paleozoic Era

Cambrian Period. . Ordovician Period. . Clastic wedge developed NW of Taconic High-lands, tidal flat and alluvial/delta sediments in-clude Red Mountain Fm. in NW Ga. and Birmingham, AL.. 5. Silurian Period. . Devonian PeriodThe presence of widespread reefs and evaporite deposits indicate the climate was uniformly warm and mild world-wide, and generally dry. .
