Abstract
Dromaeosaurids are poorly known in Europe and their fossil records are mostly postcranial remains. To date, the French faunal records of the family Dromaeosauridae include two taxa: Pyroraptor olympius and Variraptor mechinorum. Nevertheless, their taxonomic validity and phylogenetic relationships as dromaeosaurids are controversial. Here, we report a new record of a dromaeosaurid-like pedal ungual from the ‘Grès à Reptiles’ Formation (Campanian-Maastrichtian) of the Upper Cretaceous of southern France. The French specimen was assigned to cf. Dromaeosauridae on the basis of an extensive qualitative analysis. The new specimen has a strongly curved morphology with a tall, narrow cross-section, which is one of the most characteristic anatomical features of the family. Direct comparison reveals that the claw is similar to that of Pyroraptor olympius (MNHN BO001) from a stratigraphically correlated locality.

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 it
