Abstract

fetched live from OpenAlex

Konservat-Lagerstatten , deposits in which soft-bodied or lightly sclerotized fossils are preserved, are very rare in Ordovician strata. Three significant sites are known from Upper Ordovician rocks in Manitoba: at Cat Head – McBeth Point, William Lake, and Airport Cove. These sites are in two distinct sedimentary basins: the former two are in the Williston Basin, while the latter is in the Hudson Bay Basin. All three sites contain marine fossils, but each has a different assemblage that contributes a distinct piece of the diversity picture. Important groups represented at one or more of the sites include seaweeds (algae), sponges, cnidarian medusae (jellyfish), conulariids, trilobites, eurypterids, xiphosurids (horseshoe crabs), and pycnogonids (‘sea spiders’). The different biotas reflect depositional conditions at each site. Many of the fossils are unknown elsewhere in the Ordovician at the family level or higher. The province of Manitoba therefore makes a significant contribution to knowledge of Late Ordovician biodiversity. SOMMAIRE Les lagerstatten de conservation , ces sediments contenant des fossiles d’organismes a corps mou ou legerement sclerotises particulierement bien conserves, sont tres rares dans les strates ordoviciennes.  Trois sites d’importance sont connus dans des roches de l'Ordovicien superieur a Cat Head, Manitoba, soit McBeth Point, William Lake et  Airport Cove.  Ces sites sont situes dans deux bassins sedimentaires distincts : les deux premiers sont situes dans le bassin de Williston, tandis que le second est situe dans le bassin de la baie d'Hudson.  Les trois sites contiennent des fossiles marins, mais chacun presente un assemblage different, chacun montrant une composante distincte de la diversite biologique d’alors.  Les groupes les plus importants representes, dans un ou plusieurs de ces sites, sont les algues, les eponges, les cnidarian medusae (meduses), les conularides, les trilobites, les eurypterides, xiphosurides (limules) et pycnogonides.  Les differents biotopes refletent les conditions de depot de chaque site.  Nombre de ces fossiles sont inconnus ailleurs dans l'Ordovicien, au niveau de la famille ou du taxon superieur de la classification.  Ainsi, la province du Manitoba offre-t-elle une contribution importante a la connaissance de la biodiversite de l'Ordovicien superieur.

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.
