Monk's Mound at Cahokia contains Archaic period dog burial, predating Mississippian. Monk's Mound at Cahokia has colored earth veneers (clay) on all surfaces, two feet thick Dog burial on the top terrace was dated to the Archaic period (2500 BC) Paul Patenaude determined the dog matched size of Archaic dogs from his canine studies

Monk's Mound at Cahokia held a major surprise: a dog burial on the top terrace dated to the Archaic period around 2500 BC, predating the Mississippian culture by millennia. Researcher Paul Parlamy confirmed the dog matched sizes of known Archaic dogs. The mound originally stood 125 feet tall with a 22-acre base and colored clay veneers two feet thick. However, managers used backhoes in 2007, removing 30,000 cubic feet of earth despite geologists recommending slope stabilization instead.
