Red ochre burials and shell trade networks span North America from 4500-1000 BCE

Red ochre burials associated with the Red Ocher Complex were documented in the Upper Great Lakes and Greater Illinois River regions, dating primarily to the Late Archaic period. Shell artifacts found in burial contexts suggest long-distance trade connections existed across North America. Shell mounds and shell-tempered pottery appear in Kentucky, Tennessee, and northern Alabama. These Archaic-period networks demonstrate remarkable connectivity across eastern North America.

Key facts claimed:

- Red ochre burials found across North America from Kentucky and Tennessee to the northern Great Plains and California

- Conch shells imported from West Indies found in burials as far north as the Finger Lakes region

- Abalone shells from Southern California and Pacific coast distributed across trade networks

- Red ochre dog burials concentrated around Pensacola, Florida and throughout the Gulf Coast

- Shell mounds made almost entirely of shells found in Kentucky, Tennessee, and northern Alabama
