... Wood Canyon Formation. Discoidal forms referred to Nimbia occur in both the lowermost Wood Canyon Formation and the underlying strata of the Stirling Quartzite. These fossils occur directly below Lower Cambrian trace fossils, including Treptichnus pedum, and confirm the persistence of the Ediacaran...

...J. Bertrand-Sarfati; A. Moussine-Pouchkine; B. Amard; A. Aït Kaci Ahmed Abstract Ediacara-type body fossils are reported here for the first time from the West African craton in Algeria. This assemblage comprises medusoids comparable to Medusinites sp. and Nimbia , a trace fossil, and a new genus...

... to Nimbia occlusa Fedonkin, Vendetta ? sp., and Irridinitus ? sp. They occur below a glaciomarine diamictite about 2.5 km below the base of the Cambrian, and they may represent the oldest Ediacaran fossils now known. The find has implications for models that relate the evolution of the Ediacara fauna...

... identified as Nimbia occlusa ( Vidal et al. 1994 a , fig. 15f), but their relationship to other occurrences of Nimbia is inconclusive. Two possible explanations are suggested for this type of structure in the Domo Extremeño group. They could represent isolated loops of trace fossils or three...
