| Summary: | Judomia absita Fritz, 1973 (Fig. 7.1–7.6) Judomia? absita FRITZ, 1973, p. 14, pl. 8, figs. 1–11. Material examined. PWNHC-2009.20.23-2009.20.46, KUMIP-320714-320737, from Nevadella zone, Early Cambrian, Sekwi Formation, Mackenzie Mountains, Northwest Territories, Canada (Section 1, 196.1– 378 m above base of formation and in float; Section 2 in float; Section 3, lower 100 m of formation; Section 4, 195– 215 m above base of formation; Section 14 in float). Diagnosis. Glabella cylindrical; strongly incised SO conjoined adaxially; S1, S2, and S3 not conjoined adaxially; extraocular area shows some relief; posterior cephalic border length (sag.) increases adaxially. Discussion. Nelson (1976, 1978) commented on the presence of various species he referred to Judomia in the Lower Cambrian of the White-Inyo region of California. However, his definition of Judomia did not always accord with a phylogenetically constrained, monophyletic conception of the genus [see Lieberman (2001) for more detailed discussion].
