Monotypic proarticulatan genera

thumb|227x227px|Large landscape model of Spriggina floundersi, located in Arkaroola|Arkaroola Wilderness Sanctuary Spriggina is a genus of early animals whose relationship to living animals is unclear. Fossils of Spriggina are known from the late Ediacaran period in what is now South Australia. Spriggina floundersi is the official fossil emblem of South Australia; it has been found nowhere else.

Yorgia waggoneri is a discoid Ediacaran organism. It has a low, segmented body consisting of a short wide "head", no appendages, and a long body region, reaching a maximum length of . It is classified within the extinct animal phylum Proarticulata.

Praecambridium sigillum is an extinct organism that superficially resembles a segmented trilobite-like arthropod. It was originally described as being a trilobite-like arthropod, though the majority of experts now place it within the Proarticulata as a close relative of the much larger Yorgia. It is from the Late Ediacaran deposit of Ediacara Hills, Australia, about 555 million years ago. On average, P. sigillum had at least 5 pairs of segments, with each unit becoming progressively larger as they approach the cephalon-like head.

Andiva ivantsovi is a Vendian fossil, identified to be a bilaterian triploblastic animal in the Ediacaran phylum Proarticulata, known from the Winter Coast, White Sea, Russia. It was first discovered in 1977, and described as a new species in a new genus by Mikhail Fedonkin in 2002. It lived about 555 million years ago. Fossils of Andiva also occur in South Australia. All known fossils of Andiva are external molds.

Windermeria aitkeni (named after Windermere, British Columbia, Canada) is a Precambrian organism from the Blueflower Formation of Sekwi Brook North, in the Northwest Territories of Canada. Only one specimen has been found. Windermeria is a small (16.4 × 7.9 mm) segmented elongated oval fossil with eight nearly equal-sized segments arranged transverse to medial furrow in opposite arrangement. Windermeria superficially resembles a diminutive Dickinsonia and as such is the only possible dickinsoniid proarticulatan known exclusively from outside of Australia and East Europe.

Ovatoscutum concentricum is one of many enigmatic organisms known from the Ediacaran deposits of the Flinders Ranges, Australia, and the White Sea area in Russia, dating around 555 Ma.

Cephalonega stepanovi is a fossil organism from Ediacaran deposits of the Arkhangelsk Region, Russia. It was described by Mikhail A. Fedonkin in 1976.

Marywadea is an extinct proarticulate organism from the late Ediacaran of Australia. Originally described under Spriggina, it is a monotypic genus, containing only Marywadea ovata.

Armillifera parva is a species of Ediacaran proarticulate first described by Mikhail Fedonkin in 1980. Its fossils were discovered in the White Sea area, Arkhangelsk Region, Russia. These fossils of A. parva were restricted to almost the same stratigraphic range as Kimberella, although fossils of both organisms have been rarely found.
