ELLESMEREIA SCHULTZEI VIETH, 1980
(FIG. 6A–C; TABLE 1; SUPPL. 1, FIGS. 4, 5,?20)
Ellesmereia schultzei Vieth 1980, 54, figs. 26, 27, pl. 9.
Type material — Holotype GSC 2, Member A, Red Canyon River Formation, Ellesmere Island, Canada (Lower Devonian, Lochkovian).
Referred specimens —Rare scales in BCII at level 430.5’ (131.2 m) and possibly another very large scale at level 525’ (160 m): Roberts Mountains Formation.
Description and comparison —The scales at the lower levels have a broad central longitudinal ridge flanked by narrow ridges paralleling the central ridge. All ridges extend the length of the crown. The base is concave with a sub-diamond outline. The morphology conforms to that of the type scales from the Lochkovian Member A, Red Canyon River Formation, Ellesmere Island, Arctic Canada, figured by Vieth (1980, pl. 9) .
