| The name was indiscriminately applied by various later writers, but always to one of the Caddoan tribes or group of tribes. |
| The Caddoan language family includes the Caddo, Wichita, Pawnee, and Arikara languages, which are found on the central Plains. |
| The southern distribution of Cahokia-style figurines is heavily concentrated at Caddoan towns along a roughly 120-km segment of the Arkansas River valley of Oklahoma. |
| No other contemporaneous mortuary vessel assemblages from other sites across the Caddoan area resemble those of the Titus phase. |
| Unfortunately, the last published glottochronology for all the Caddoan languages dates to the 1960s, before the technique was refined. |
| If such a network existed, we would expect the pattern to more closely resemble that recorded for the Caddoan region. |
