Caddoan

They spoke a Caddoan language, one related to that of the Arikara, Pawnee and Wichita.

The Caddoan works were discovered in 1980 along the Red River in Lafayette County while Army Corps of Engineers employees were working on a river containment project.

The Caddoan family is less clearly defined than either of the preceding, but evidently consisted of many small tribes grouped, and forming confederacies.

The earth-covered house probably originated with the tribes of Caddoan stock, that is, the Pawnee and Arikara, and was adopted by the tribes of other stocks upon their migration into the Missouri River region.

The Caddoan peoples seem to have been on the southern plains from earliest times.
