The châtelperronian Neandertals of Cova Foradada (Calafell, Spain) used Iberian imperial eagle phalanges for symbolic purposes
Bibliographic record
Abstract
The use of personal ornaments by Neandertals is one of the scarce evidence of their symbolic behaviour. Among them stand up the eagle talons used presumably as pendants, in an analogous way than anatomically Modern Humans ( Homo sapiens ) did. Considering the broad range and time scale of Neandertals distribution across Eurasia, this phenomenon seems to be concentrated in a very specific area of Southwestern-Mediterranean Europe during a span of ca. 80 ka. Here we present the analysis of one pedal phalange of a large eagle recovered in Foradada cave site, Spain. Our research confirms the use of eagle talons as symbolic elements in Iberia, expanding geographically and temporally one of the most common evidence of symbolic behaviour among western European Neandertals. The convergence in use of large raptor talons as symbolic elements by one of the last Neandertal populations raises the survival of some cultural elements of the Middle Paleolithic into beginnings of the Upper Paleolithic.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
