A compendium of radiocarbon and oxidizable carbon ratio dates from archaeological sites in East Texas, with a discussion of the age and dating of select components and phases.

Timothy K Perttula


This paper presents a compilation of the >520 radiocarbon and oxidizable carbon ratio dates obtained since the early 1950s from archaeological sites in East Texas. Many of the dates are from difficult-to-obtain sources, such as archaeological sites investigated during the course of cultural resource management projects. An analysis of the age ranges in the dates indicate that most pertain to prehistoric and protohistoric Caddoan Indian occupations, particularly the Early (AD 1000-1200) and Middle Caddoan (AD 1200-1400) periods when prehistoric Caddoan settlements were widely distributed throughout the region.
