This excellent Website from the University of Arizona focuses on the branch of science known as palynology, in which researchers study the microscopic remains of plants and organisms to reconstruct ecological conditions of the past. The site features a wealth of information, including research projects (and publications) from the University of Arizona; background information (and illustrations) describing palynomorphs and archaeological, Quaternary, and stratigraphic palynology; links to scientific and general palynology Websites; a subject-organized list of select palynology references; links to international palynology organizations; and much more.
