PALAEOSCENIDIIDAE (RADIOLARIA) FROM THE LOWER SILURIAN OF THE CAPE PHILLIPS FORMATION, CORNWALLIS ISLAND, NUNAVUT, CANADA
Bibliographic record
Abstract
Abstract Spicular radiolarians of the family Palaeoscenidiidae were recovered from the Llandovery to lower Wenlock of the Cape Phillips Formation, Nunavut, Canada. Several changes are made to the classification of these radiolarians. Goodbodium rarispinosum (Goodbody, 1986) was previously placed with Palaeoscenidium Deflandre, 1953. Insolitignum MacDonald, 1999 is emended to allow for additional apical rays. Insolitignum cancellatum (Goodbody, 1986) includes species which were previously assigned to Palaeoscenidium, Palaeotripus Goodbody, 1986, and Palaeoephippium Goodbody, 1986, owing to the variable development of one ray. Insolitignum peranima MacDonald, 1999 is synonymized with I. dissimile (Goodbody, 1986). Palaeodecaradium apertum (Goodbody, 1986) was previously placed with Palaeoscenidium; Palaeotripus nudus Goodbody, 1986 is considered a synonym of P. apertum. Palaeoephippium is rediagnosed based on the branching of the basal rays; the new diagnosis also allows for more than six rays and in orientations other than originally diagnosed. Palaeoephippium aranea Goodbody, 1986 is a junior synonym of P. bifurcum Goodbody, 1986. Palaeoephippium reteforme Goodbody, 1986 and P. ramipendentes Goodbody, 1986 are synonymized with P. radices Goodbody, 1986. Palaeotripus monospinosum Goodbody, 1986 is synonymized with Palaeoephippium spinosum Goodbody, 1986. One new species, Palaeodecaradium gordoni, is described. It possesses six rays; the apical rays are long and curved. The basal rays bear spinules on their lateral margins.

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.
