Gravettian sites generally date between 33,000 and 20,000 BP. The Solutrean culture was located in eastern France, Spain, and England. Solutrean artifacts have been dated c. 22,000 to 17,000 BP.

The objects and archaeological sites presented in the Museum’s Timeline of Art History for the time period 20,000–8000 B.C. illustrate diverse examples of prehistoric art from across the globe. All were created in the period before the invention of formal writing, and when human populations were migrating and expanding across the world.

This timeline of human prehistory comprises the time from the first appearance of Homo sapiens in Africa 200,000 years ago to the invention of writing and the beginning of history approximately 5,500 years ago. It covers the time from the Middle Paleolithic (Old Stone Age) to the very beginnings of the Bronze Age.

The people that made these paintings were among the very first humans to arrive in the Americas. Scientists estimate the paintings as more than 22,000 years old—which supports emerging theories, based on other archaeological findings, that humans occupied the Americas around 20,000 to 30,000 years ago.

By 20,000 years BCE, evidence clearly shows Homo Sapiens inhabited all the major continental land masses of the earth, including Africa, Australia, Eurasia, and the Americas, but excluding Antarctica which has never had a self-sustaining human population for obvious reasons.
