Abstract
History of development of the American Formative concept is briefly outlined. A chronology is presented that covers the three millennia before the Christian Era and which extends from Ecuador to the Ohio Valley. The Stalling’s Island complex of fiber-tempered pottery from the coast of Georgia is compared with the Valdivia Period ceramics of Ecuador, and the Orange fiber-tempered wares of Florida are compared with the Machalilla Period ceramics of Ecuador and related material in Mesoamerica. The conclusion is drawn that these early Southeastern Cultures ultimately derived from the Ecuadorian early Formative by way of colonies that probably existed in the southern part of Mesoamerica.
