At Altamira (Cantabria, Spain), the most recent excavated levels are Magdalenian, dated by radiocarbon to roughly 19,000–16,800 years (cal BP). These levels help show how Magdalenian groups lived and made art during a time of major environmental change at the end of the last ice age.
As the Last Glacial Maximum (LGM) eased, human groups in western Europe were still concentrated in relatively milder “refugia” (sheltered regions where people, plants, and animals could survive). Out of these areas, a new Late Upper Paleolithic tradition—the Magdalenian—emerged, setting the stage for wider reoccupation as climates improved.
The Magdalenian developed after the Solutrean, bringing clear shifts in toolmaking and symbolic practices. Hunters relied heavily on bone and antler equipment (such as spear points), along with specialized stone tools like burins (chisel-like tools) and bladelets, reflecting new ways of working materials and organizing daily life.
Across the Franco-Cantabrian zone (southwestern France and northern Spain), Magdalenian sites and art become especially dense, indicating strong, repeated use of key valleys, caves, and rock shelters. This region acted as a major base for later expansion northward and eastward as ice sheets retreated and habitats opened up.
The Hamburgian culture (about 15,500–13,100 BP), often described as part of a broader Magdalenian-related group, is known from reindeer-hunting sites across the North European Plain. Its spread helps illustrate how Late Upper Paleolithic groups tracked cold-adapted herds close to the margins of shrinking ice sheets.
After long gaps in settlement during peak glacial conditions, Magdalenian-linked groups reoccupied parts of northwest Europe. Evidence from archaeology shows Magdalenian/Creswellian/Hamburgian traditions becoming part of a more lasting presence in areas around the southern North Sea basin as conditions improved.
The Bølling–Allerød Interstadial (about 14,690–12,900 BP) brought rapid warming in the Northern Hemisphere. As glaciers retreated and vegetation spread, the changing environment increased opportunities for people to move into areas that had been too cold or ice-covered earlier.
In Britain, the Creswellian (often called British Late Magdalenian) dates to about 13,000–11,800 BP. It shows that people returned to and used parts of Britain during the Late Glacial, likely connected to wider Magdalenian-related movement networks across northwestern Europe.
The Younger Dryas (about 12,900–11,700 BP) brought a sharp return to colder conditions in the North Atlantic region. This climate reversal likely reduced populations in some northern zones and shifted settlement patterns, changing how Late Upper Paleolithic groups used the southern North Sea region and nearby areas.
As Magdalenian traditions ended, the Azilian (about 12,500–10,000 BP) became prominent in parts of northern Spain and southern France. Toolkits shifted toward smaller microliths (tiny stone inserts for composite weapons), while art often moved away from large cave images toward simpler geometric designs, including painted pebbles.
Late in the Magdalenian sequence, barbed harpoons become a well-known tool form, reflecting intensified use of aquatic and riverine resources in some regions. This shift fits a broader pattern of diversification in equipment and subsistence strategies as landscapes, rivers, and coastlines changed during deglaciation.
With the end of the Younger Dryas and the start of the Holocene (beginning about 11,700 BP), warmer and more stable climates supported new plant and animal communities across western Europe. In this setting, Magdalenian lifeways had already transformed into later traditions (including Azilian), marking a clear endpoint to Magdalenian reoccupation and expansion during the Late Glacial.
