8,000-Year-Old Cave Man Found in Asturias: His Diet Revealed 2026

An 8,000-year-old cave man found in Asturias, Spain, is so well preserved that researchers have determined what he ate: about 55% of his protein came from the sea. The discovery in Sohornu cave, near Andrín on the Asturian coast, offers a rare window into Mesolithic life centuries before farming reached the region.

The find was announced by the Archaeological Museum of Asturias after a rescue excavation that concluded in summer 2025. The remains include a remarkably intact skull and other bones of a man who died around age 45.

What Was Found in Sohornu Cave?

Two speleologists, Pablo Solares and Clara Zazo, first spotted a human jawbone next to a shell mound in 2024. They alerted heritage authorities, leading to a rescue dig directed by Pablo Arias of the University of Cantabria and Alberto Martínez Villa.

The excavation uncovered remains of at least two adult males, a deer antler, and evidence of cave occupation spanning from 12,000 to 4,300 years ago. The exceptional preservation of the skull and bones allowed scientists to analyze dietary proteins.

The Asturian Culture and Shell Mounds

The remains belong to the Asturian culture, defined in 1923 by the Count of Vega del Sella based on shell mounds called concheros. These mounds are piles of discarded shells that accumulated over generations of coastal foraging.

The Asturian people were hunter-fisher-gatherers who thrived along the northern coast of Spain before the arrival of agriculture and livestock. Their reliance on marine resources is a defining characteristic.

Why Is This Discovery Important?

This finding provides concrete evidence of the diet of Mesolithic coastal populations in Iberia. The 55% marine protein figure is unusually precise for such an ancient individual, thanks to stable isotope analysis.

It confirms that these communities were skilled mariners and shellfish collectors, not merely opportunistic scavengers. The cave served as a time machine, preserving a snapshot of daily life eight millennia ago.

What Did the 8,000-Year-Old Man Eat?

His diet was heavily marine-based, with more than half of his protein intake coming from the sea. This likely included fish, shellfish, and possibly marine mammals.

The remaining protein came from terrestrial sources such as deer and other game, as indicated by the deer antler found in the cave. The balance shows a mixed but sea-oriented economy.

• About 55% of protein from marine sources.
• Remains of at least two adult males found.
• Cave occupation dated between 12,000 and 4,300 years ago.
• Analysis results expected at the end of the year.
• Culture: Asturian, known for shell mounds.

How Does This Compare to Other Ancient Diets?

Mesolithic diets in coastal Europe varied, but marine reliance was common where resources were abundant. The Asturian case stands out for its clear signal and excellent preservation. The longer history behind the story is traced in Hoy No Circula Saturday: Which Cars Can Drive on October.

This table illustrates the range of marine dependence across Mesolithic Europe. The Sohornu individual falls within the higher end, highlighting the richness of the Asturian coast.

Further analyses are planned for the end of the year, which may reveal more about his health, mobility, and exact diet. The museum plans to display the findings, bringing this ancient story to the public. A closer look at the same subject appears in Etruscan Tombs Designed for a Cathedral Effect 2,500 Years Ago.

For now, the 8,000-year-old man from Sohornu cave reminds us that human history is written not only in stone and bone but also in the meals we once ate.
