Discuss the paleogeography of the Early Paleozoic. How did this paleogeography differ from
present-day geography? What will be an ideal response?
The student should recognize that the Early Paleozoic continents were different from the presentday
continents. Many of the tectonic features that we recognize today were the result of later
tectonic events. The continents in the Early Paleozoic were in different latitudes than presentday
continents resulting in different climate conditions.
