The discovery of the Clovis culture in New Mexico pushed the settlement of North America back to what archeologists believed were the first people to cross a land bridge between Siberia and Alaska at the end of the last Ice Age. The culture is named for artifacts found near Clovis, New Mexico. What is known about the Clovis people comes from the remains they left behind, which are mostly tools: scrapers, drills, blades, and distinctive leaf-shaped, fluted spearpoints called Clovis points. The archaeologists differentiate them, especially for the shapeof the carving of some arrowheads of great size, with a peduncle, that is to say, they had with a lower part in the form of a fish tail, well carved by both sides.It is known that this technology appeared in the period between 13,000 and 11,000 years, and spread rapidly.
