Bolbolenellus sp.

Fig. 3.3, 3.4

Material examined. KUMIP 355561.

Discussion. Fritz (1972) suggested his Olenellus sp. 4 was similar to B. altifrontatus ( Fritz, 1972) . This specimen was compared with both species and it appears to be more similar to B. altifrontatus . It does differ however from B. altifrontatus in having somewhat more prominently incised S1-S3, but this might be attributable to the fact that the specimen medially is somewhat weathered. As we only have a single incompletely preserved specimen, we are leaving it in open nomenclature.

Occurrence. Olenellus zone or Waucoban Series, Dyeran stage, sensu Webster (2011a, b) and Webster et al. (2011), early Cambrian, Sekwi Formation, Mackenzie Mountains, Northwest Territories, Canada, Sekwi Formation, Mackenzie Mountains, Northwest Territories, Canada, Section 4, 710– 720 m above the base of section.
