Clovis complex, ancient culture that was widely distributed throughout North America. It is named for the first important archaeological site found, in 1929, near Clovis, N.M. Clovis sites were long believed to have dated to about 9500 to 9000 bc, although early 21st-century analyses suggest the culture may have been of shorter duration, from approximately 9050 to 8800 bc.

The Clovis complex is generally considered to be ancestral to the Folsom complex. Clovis and Folsom were hunting-and-gathering cultures; although both groups were fairly generalized foragers, Clovis people seemed to have preferred to eat Pleistocene megafauna such as mammoths, while Folsom people seem to have preferred an extinct species of giant bison.

Associated with Clovis are such implements as bone tools, hammerstones, scrapers, and projectile points. The typical Clovis point is leaf-shaped, with parallel or slightly convex sides and a concave base. The edges of the basal portions are ground somewhat, probably to prevent the edge from severing the hafting cord. Clovis points range in length from 1.5 to 5 inches (4 to 13 centimetres) and are heavy and fluted, though the fluting rarely exceeds half the length. Some eastern variants of Clovis—called Ohio, Cumberland, or Suwannee, depending on their origin—are somewhat fish-tailed and also narrower relative to length.

Folsom complex, an early archaeological complex of North America, characterized by a distinct leaf-shaped projectile point called a Folsom point. The Folsom complex of artifacts, which also includes a variety of scrapers, knives, and blades, was one variety of the Paleo-Indian hunting cultures. It centred in the Great Plains and persisted from approximately 9000 to 8000 bce. Folsom people were generalized hunters and gatherers, although they also hunted a now-extinct form of giant bison (Bison antiquus). Much of the importance of the Folsom complex derives from the fact that the initial scholarly excavation at Folsom, N.M., in 1926 (the site was discovered in 1908), marked the first association in the Americas of man-made artifacts with the bones of megafauna from the Pleistocene Epoch (about 2,600,000 to 11,700 years ago); until this discovery, scholarly consensus had held that humans did not reach the Americas until perhaps 4,000 years ago. (See also Clovis complex.)

The classic Folsom point is more or less leaf-shaped, or lanceolate, with a concave base, projecting ears at the basal corners, and fluted sides. In addition, the Folsom complex includes unfluted points, blunt-tipped knives, scrapers, and bone tools. Most Folsom artifacts have been discovered in various parts of the Great Plains. The majority of datable artifacts seem to fall in the period between 9000 and 8000 bce.
