Loganellia undetermined



( TABLE 1; SUPPL. 1, FIGS. 1 View Figure 1 , 4 View Figure 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.
