The literature was reviewed for information about the history of southern vegetation. There are already several reviews of this material. The better treatments of the subject include Delcourt and Delcourt (1993), Mac and others (1998), Ricketts and others (1999), and Stein and others (2000). An extensive and detailed primary literature exists on the paleobotany of the region based on palynology (the study of ancient pollen). Only a small portion of that information was used in this work, but anyone interested in further reading can consult the reviews of Watts (1980) and Delcourt and Delcourt (1998).
