Overview
- The find was presented in Navarra after recovery in October 2025 during a government-led intervention at Sima Arrafela with university and museum partners.
- Radiocarbon dating and a copper point lodged between the ribs place the animal in the Late Chalcolithic and indicate prehistoric hunting.
- Preliminary morphology suggests a European bison, though genetic results could instead align it with the so-called Clade X.
- Researchers estimate a young adult male of about four years weighing more than 800 kilograms.
- Cleaning, inventory and sampling for genetic and diet studies are complete, with comprehensive results expected within a year and potential exhibition under review.
