Reconstruction
Cueva de los Azules lies near the confluence of the Sella and Güeña rivers at Cangas de Onís, rather than directly on the Asturian coast. Excavations begun in 1973 exposed a long Azilian sequence and, in 1974–1975, an exceptional grave near the cave entrance. The deceased was an adult man, probably older than forty, placed on his back in a purpose-dug pit. Ochre colored the grave floor and skeleton, while earth, rounded stones, and slabs covered the body. This is one of the rare formal burials known from the Azilian world of northern Iberia.
The burial has not been dated directly. Conventional radiocarbon measurements from layers above and below it once placed it broadly in the first half of the ninth millennium BCE. Those measurements had large uncertainties, however. A 2025 reassessment excluded the old determinations from its preferred chronology and dated sampled portions of the cave's Azilian sequence to approximately 14,080–12,710 calibrated years BP, or about 12,130–10,760 BCE. Because the new samples were not taken from the skeleton, the burial's exact age remains unresolved, but 7500–7000 BCE is not supported by the published stratigraphy.
Objects beside the man included stone scrapers, backed bladelets, burins, flakes, cores, hammerstones, antler harpoons or fragments, painted cobbles, a badger skull, and a fitted cluster of marine mussel shells described as modiolas. These shells had to be carried inland, but their presence does not demonstrate a funerary meal: they may have been food remains, personal objects, offerings, or symbols. Likewise, the harpoons could represent working equipment or deliberately selected grave goods. Both possibilities are scholarly interpretations rather than direct observations of ritual meaning.
Food evidence from the wider cave is clearer but still incompletely studied. Preliminary faunal reporting indicates that red deer dominated the Azilian mammal assemblage, followed by chamois, wild boar, roe deer, caprines, and horse; unidentified fish were also recovered. These remains describe hunters and gatherers drawing on river valleys, woodland edges, and uplands. The tools imply carcass processing and the maintenance of hunting or fishing equipment, but no comprehensive study yet establishes particular recipes, cooking temperatures, or meal combinations at Los Azules.
Los Azules therefore records both subsistence and social action: animal foods sustained repeated occupations, while selected shells, animal remains, tools, ochre, and painted stones were gathered into a carefully constructed grave. Later Asturian shell middens document much more intensive coastal harvesting of limpets, top shells, mussels, and sea urchins. That development provides regional context, not proof of a direct cultural lineage. Game, river fish, and shellfish remain foods of northern Spain today, but no specific modern dish can securely be traced to this burial.
Historical context
Northern Iberia was passing through the climatic instability at the end of the last Ice Age. The securely redated Azilian sequence at Los Azules spans temperate Late Glacial conditions and the colder Younger Dryas, before the Holocene began around 9700 BCE. Mobile hunter-gatherers used the Sella corridor between the Cantabrian coast and mountain interiors, hunting large and medium game and exploiting fish and marine resources. Farming, domestic livestock, and pottery had not yet entered the regional food system; those changes arrived several millennia later.
Evidence
Archaeological
StrongExcavation directly documented a purpose-dug grave, an articulated adult male skeleton, ochre, stone coverings, lithic artifacts, antler objects, painted cobbles, marine shells, and associated animal remains.
Zooarchaeological
ModeratePreliminary work identifies an Azilian macrofauna dominated by red deer, with chamois, wild boar, roe deer, caprines, and horse, plus unidentified fish. The 2022 synthesis stresses that the cave's fauna has not received a comprehensive modern study.
Food identification
ModerateThe animal taxa and marine mussel shells are identified sufficiently to demonstrate access to terrestrial and aquatic resources. It remains uncertain which burial-associated remains were food, equipment, offerings, ornaments, or incidental material.
Dating
LimitedThere is no direct radiocarbon determination on the buried individual. Legacy dates bracketing the grave have large errors, while high-precision dates published in 2025 revise the broader Azilian sequence substantially earlier without directly dating the burial.
Preparation method
LimitedScrapers, bladelets, burins, hammerstones, antler objects, and faunal remains support processing activities, but specific cooking methods or recipes have not been established.
Geographic attribution
StrongThe cave is securely located at Contranquil, Cangas de Onís, near the confluence of the Sella and Güeña rivers in eastern Asturias.
Historical interpretation
InterpretiveInterpretations of the grave goods as a personal toolkit, funerary offerings, evidence of group care, or symbols of identity are plausible scholarly readings but cannot be observed directly.
Visual reconstruction
ProbableThe body's position and major grave architecture are documented, but erosion, animal disturbance, water movement, and skeletal damage prevent a completely certain reconstruction of the original arrangement.

Limitations
- majordate start/date end
The supplied 7500–7000 BCE range is unsupported. The burial has no direct date; legacy bracketing estimates placed it broadly around 9250–8350 BCE, while a 2025 high-precision reassessment dates sampled portions of the Azilian sequence substantially earlier, approximately 12,130–10,760 BCE.
- moderatedescription
Los Azules is an inland cave beside the Sella-Güeña river confluence, not a documented shell-rich coastal midden. A cluster of transported marine mussel shells occurred in the grave, but its function and relationship to food consumption are uncertain.
- moderateepoch name/title
Calling the burial straightforwardly Mesolithic and postglacial is problematic. Recent AMS chronology places the securely dated Azilian sequence in the final Pleistocene, although older literature assigned the undated burial to the earliest Mesolithic or initial Holocene.
