A Systematic Revision of the Late Furongian Trilobites from Cerro Pelado, Mendoza, Argentina
Bibliographic record
Abstract
Late Furongian (late Cambrian) trilobites are described from the black, deep water limestones of the El Relincho Formation in Cerro Pelado, Precordillera of Mendoza, western Argentina. In addition, selected type specimens of the Carlos Rusconi collections at the Museo de Ciencias Naturales y Antropológicas J.C. Moyano, (Mendoza) are revised. The assemblages are largely dominated by the agnostoid Lotagnostus peladensis (Rusconi), which proved to be a species with variably effaced dorsal furrows. Polymeroids include Mendoparabolina pirquinensis Rusconi, Hungaia peladensis Rusconi, and Loganellus cf. macropleurus Rasetti, as well as some fragmentary remains of uncertain affinities. Generic occurrences strongly support connections with Laurentia. Although the species identified are endemic to the southern Precordillera, they mostly resemble faunas from the lower Saukia Zone of western North America, and the Onchonotus richardsoni and Keithia subclavata faunas of eastern Canada and USA.
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
