摘要:
Two new specimens ofRangea schneiderhoehniGürich 1930 and a new fossil are here described from the Nama Group of South West Africa. A careful study of the twoRangeaspecimens and a reexamination of the holotype shows thatR. schneiderhoehniforma plana andR. schneiderhoehniforma turgida are the same species as already suggested by Gürich, Richter, and Pflug, that the puzzling outer flange of forma plana is part of an underlying second leaf‐like body, and that the Ediacara‘Rangea’does not belong to the genusRangea. Here, therefore, it is introduced as the genusGlaessnerina. The new fossil,Nasepia altae, is related toPteridinium simplexGürich 1930 andRangea schneiderhoehniGürich 1930, and also to the problematic fossilNamalia villiersiensisG
