Abstract
Summary The new fossil family Grandoculidae fam. n. is erected for a Cretaceous (Campanian) Canadian amber spider Grandoculus chemahawinensis formerly placed tentatively in the extinct family Lagonomegopidae. Following the descriptions of several new lagonomegopid genera from widespread fossil deposits, it is now clear that their overall somatic morphology is rather homogeneous and different from that of Grandoculus, which now sits uncomfortably alongside them. The enlarged first leg with a dense scopular brush of hook-tipped setae on metatarsus I represents a distinct autapomorphy for Grandoculidae. These may indicate possible relationships to non-lagonomegopid taxa such as Palpimanidae (although their scopulae consist of spatulate setae), but additional better preserved fossils (preferably mature males) will be required to confirm this.

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
