Answering the question of what Fourche Maline is has long been hampered by lack of consensus on the terminology and chronology within the ancestral Caddoan area of the four corners area of southeast Oklahoma, southwest Arkansas, northeast Texas and northwest Louisiana. To address this problem an evolution of the Oklahoma concept of Fourche Maline is presented, and developing a new chronology based on seriation of temporally sensitive artifact categories is discussed. It is concluded that Fourche Maline is a solely Woodland period culture, with a chronology that makes identifying changes over time possible. This conclusion will facilitate the understanding of Fourche Maline within the Caddon homeland.
