during the time of the acadian orogeny, middle devonian (385 ma), the paleolatitude of the laurentia was in the southern hemisphere near the equator, between 0° to 30°s latitude. laurentia did not change much with respect to paleolatitude during the devonian. gondwana, on the other hand, traveled a large distance, such that in the ordovician the south pole was located in northern africa, where it then moved west of southern chile during the silurian, and moved back to central africa during the devonian. however, more recent research, from scotese & mckerrow, suggests that in late devonian, the south pole was in north-central argentina rather than northern africa, which was supported with paleoclimatic evidence. the paleolatitude of gondwana during the middle to late devonian resided around intermediate latitudes of about 50°s.
