It took over 20,000 years for the sea to transition from the LGM shoreline up to the modern coast of Florida. As ocean water covered the ancient landscape from about 26,000 to 5,000 years ago, several distinct and profound changes occurred simultaneously: the landmass of Florida became greatly reduced with significant changes to the contours of the state’s coastlines; the surficial water aquifer and deeper Floridian aquifer became elevated; weather patterns changed; and biotic (i.e., plant and animal) communities rearranged themselves on the landscape, with some species flourishing, others staying the same, and several (like the mastodon) becoming extinct.
