Early Eocene rodents (Mammalia) from the Eureka Sound Group of Ellesmere Island, Canada
Bibliographic record
Abstract
Rodents are a minor element in the Early Eocene terrestrial fauna from the Eureka Sound Group of Ellesmere Island. Nevertheless, at least five taxa can be recognized, all members of the family Ischyromyidae. Two are paramyines, of which one is described as Paramys hunti, sp. nov. Three of the rodents are microparamyines, Microparamys bayi, sp. nov., and two species of the new genus Strathcona, S. minor, sp. nov., and S. major, sp. nov. The paramyines are Holarctic in distribution in the Early Eocene, but the microparamyines are known only from North America and Europe. The Arctic Microparamyinae provide the first clearly documented case for an early Cenozoic mammalian taxon having a North American origin and later dispersal into Europe across a North Atlantic terrestrial biogeographic province.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
