Bailiella aff. B. tenuicincta – Martin & Dean 1988: 19, pl. 2, figs 7, 12. Bailiella cf. tenuicincta – Chirivella Martorell et al. 2015: 177, figs 4A-I; p. 179, figs 5A, B. LECTOTYPE. — Specimen no. SGU 4524, Swedish Geological Survey (Sveriges Geologiska Undersökning), Uppsala, Sweden, originally figured in Linnarsson (1879) and designated as lectotype by Westergård (1950). From the Exsulans Limestone Bed, Tomagnostus gibbus Zone, Gislöv, on the shore 1 km south of Brantevik, Scania, Sweden. DIAGNOSIS. — Anterior margin narrow; glabella with three pairs of shallow to faint furrows; occipital ring with node; dense fine granulose ornamentation with scattered small granules (based on Linnarsson 1879, with modifications). MATERIAL EXAMINED. — Four cranidia of Bailiella tenuicincta (NFM F-2972; NFM F-3168; NFM F-3169; NFM F-3200). All specimens range between 8.52 and 16.67 m (Fig. 2) of the Manuels River Formation, type locality, Conception Bay South, Newfoundland, Canada. OCCURRENCE. — Bailiella tenuicincta is a rare middle Cambrian taxon, documented from southeastern Canada, eastern Newfoundland, in the Paradoxides hicksi and Paradoxides davidis Zones (Hutchinson 1962; Martin & Dean 1988). The taxon also occurs in Sweden (Ptychagnostus (Triplagn.) gibbus Zone; Westergård 1950, 1953), Bornholm in Denmark, (Ptychagnostus (Triplagn.) gibbus Zone; Westergård 1950; Agnostus atavus Zone; Weidner & Nielsen, 2014) and Spain (upper Badulesia tenera to lower Badulesia granieri zones; Chirivella Martorell et al. 2015). DESCRIPTION The cranidia range from 7.0 mm to 34.0 mm in width and 4.4 mm to 18.0 mm in length, while the glabella varies from 2.5 to 10.0 mm in width and 2.8 to 10.5 mm in length. All specimens are well to very well-preserved internal casts. One specimen (NFM F-2972) has two to three pairs of faint glabellar furrows. Posterior pair is aligned towards the occipital ring. REMARKS The species is closely related to B. aequalis as discussed above. According to Weidner & Nielsen (2014) the stratigraphic range of B. tenuicincta is similar to that of Bailiella impressa (Linnarsson, 1879), from which it differs in having an evenly convex cranidium and shallow axial and border furrows. Westergård (1950) figured three cranidia and one pygidium. Granulation of the pygidium (Westergård 1950: pl. 5, fig. 9) corresponds to that of the cranidia and is therefore assigned to the species, but this assignment is here considered questionable. A cranidium illustrated by Rudolph (1990: 19, text-fig. 4) may correspond to B. tenuicincta, but the resolution of the image is too low to evaluate the assignment and is therefore questionable.

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.
