Abstract

fetched live from OpenAlex

The Early–Middle Cambrian Mount Cap Formation, NWT, hosts a diverse range of exceptionally preserved fos sils. Like the celebrated Burgess Shale of British Columbia, the Mount Cap contains carbonaceous compression fossils of animals that lacked mineral ized hard parts, as well as the fully articulated skeletons of shelly taxa. Its unique importance, however, lies in exceptional carbonaceous preservation at a microscopic scale. Acid-extracted microfossils from the ‘Little Bear biota’ of the Mackenzie Mountains reveal important details of problematic groups including chancelloriids and hyolithids, and provide direct evidence of Cambrian diets in the form of fae cal strings. A complementary microfos sil assemblage from the subsurface of the Colville Hills region contains an extraordinary diversity of exquisitely preserved arthropod cuticle, and con stitutes the oldest known record of complex crown-group crustaceans. We discuss the wider significance of the Mount Cap fossils, and describe some new forms that point to the potential for future discoveries.

Full frame distilled prediction

Teacher imitation

Not 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.
