New Middle Pleistocene Hominin Dental Remains From Velika Balanica, Serbia
Bibliographic record
Abstract
ABSTRACT Objective The cave site of Velika Balanica in Sićevo Gorge, Serbia, has previously yielded early Neanderthal dental remains from Layer 3a, dated by thermoluminescence to 285 ± 34 and 295 ± 74 ka. We describe and compare four additional dental specimens recovered from the Middle Pleistocene Layers 3a and 3b of the cave: a right I 1 (BH‐8), a right I 2 (BH‐7), an incisor crown fragment (BH‐16), and a left M 3 (BH‐15). Material and Methods The fossil teeth were scanned using micro‐computed tomography (μCT), and the resulting digital models were used to record dimensions and assess internal morphology, including the enamel–dentine junction (EDJ). Morphological traits were analyzed on both outer and internal surfaces. Dental measurements were compared to those of relevant hominin samples. Results BH‐8 and BH‐7 show large, robust crowns and roots, consistent with Pleistocene Eurasian hominins. Linear enamel hypoplasia is present in BH‐8 and BH‐16. BH‐15 displays a continuous middle trigonid crest—a trait considered diagnostic of the Neanderthal lineage. Notably, BH‐15 also presents an extreme case of taurodontism, as well as a severe antemortem tooth fracture accompanied by multiple pulp stones, which are rarely recorded in the hominin fossil record. Discussion These findings align with earlier results, reinforcing evidence for early Neanderthal presence at Velika Balanica around 300 ka. While Neanderthals may have been present in the region earlier, this represents the earliest dated evidence of their spread into the Balkans.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
