LOGANELLIA FREDHOLM, 1990

Type species — Thelodus scoticus Traquair, 1898 .

LOGANELLIA SP. CF. L. CUNEATA

(TABLE 1; SUPPL. 1, FIGS. 1, 4)

Referred specimens —One scale from BCII level 27’ (8.2 m); two scales from level 430.5’ (131.2 m): Roberts Mountains Formation.

Description and comparison —Elongate teardrop-shaped scales with two sharp crown ridges. The base is oval and extends about two-thirds crown length. There is no anterior basal spur.

This scale resembles those described as Loganellia cuneata (Gross 1947, pl. 3; 1967, pl. 3) from the Přidolí of Britain, Europe, and Russia (Märss et al. 2007) but also is similar to the much older L. sulcata and L. prolata (Märss et al. 2002) from the Lower Silurian of arctic Canada. Without more material, the designation can only be tentative.
