"Solutrean" is named after the type-site of Crôt du Charnier at Solutré in the Mâcon district, Saône-et-Loire, eastern France, and appeared around 21,000 BP. The Solutré site was discovered in 1866 by the French geologist and paleontologist Henry Testot-Ferry (second son of Napoleon's famous cavalryman, General Claude Testot-Ferry, Baron of the Empire). It is now preserved as the Parc archéologique et botanique de Solutré.
The industry was named by Gabriel de Mortillet to describe the second stage of his system of cave chronology, following the Mousterian, and he considered it synchronous with the third division of the Quaternary period. The era's finds include tools, ornamental beads, and bone pins as well as prehistoric art.
Solutrean tool-making employed techniques not seen before and not rediscovered for millennia. The Solutrean has relatively finely worked, bifacial points made with lithic reduction percussion and pressure flaking rather than cruder flintknapping. Knapping was done using antler batons, hardwood batons and soft stone hammers. This method permitted the working of delicate slivers of flint to make light projectiles and even elaborate barbed and tanged arrowheads. Large thin spear-heads; scrapers with edge not on the side but on the end; flint knives and saws, but all still chipped, not ground or polished; long spear-points, with tang and shoulder on one side only, are also characteristic implements of this industry. Bone and antler were used as well.
The Solutrean may be seen as a transitory stage between the flint implements of the Mousterian and the bone implements of the Magdalenian epochs. Faunal finds include horse, reindeer, mammoth, cave lion, rhinoceros, bear and aurochs. Solutrean finds have been also made in the caves of Les Eyzies and Laugerie Haute, and in the Lower Beds of Creswell Crags in Derbyshire, England. The industry first appeared in what is now Spain, and disappears from the archaeological record around 17,000 BP.
The Solutrean hypothesis builds on similarities between the Solutrean industry and the later Clovis culture / Clovis points of North America, and suggests that people with Solutrean tool-technology crossed the Ice Age Atlantic by moving along the pack ice edge, using survival skills similar to those of modern Eskimo people. The migrants arrived in northeastern North America and served as the donor culture for what eventually developed into Clovis tool-making technology. Archaeologists Dennis Stanford and Bruce Bradley suggest that the Clovis point derived from the points of the Solutrean culture of southern France (19,000 BP) through the Cactus Hill points of Virginia (16,000 BP) to the Clovis point. The idea of a Clovis-Solutrean link remains controversial and does not enjoy wide acceptance. The hypothesis is challenged by large gaps in time between the Clovis and Solutrean eras, a lack of evidence of Solutrean seafaring, lack of specific Solutrean features in Clovis technology, the difficulties of the route and other issues.
In 2014, the autosomal DNA of a 12,500+-year-old infant from Montana was sequenced. The DNA was taken from a skeleton referred to as Anzick-1. The skeleton was found in close association with several Clovis artifacts. Comparisons showed strong affinities with DNA from Siberian sites, and virtually ruled out any close affinity of Anzick-1 with European sources (see the "Solutrean hypothesis"). The DNA of the Anzick-1 sample showed strong affinities with sampled Native American populations, which indicated that the samples derive from an ancient population that lived in or near Siberia, the Upper Palaeolithic Mal'ta population.
