Definitions
adj
Of a geologic period within the Neoproterozoic era from about 620 to 542 million years ago.
The widespread discoveries of fossil remains of Ediacaran aspect have generated continued excitement in respect of their possible evolutionary significance, and in terms of recent surrealistic interpretations of their morphology and inferred interrelationships (Pflug, 1970a,b, 1972a,b; Fedonkin, 1985 a,b; Gould, 1984, 1985; Seilacher, 1984, 1985, 1989; McMenamin, 1986; and Bergstrom, 1989, 1990), a reexamination of the actual fossil material is timely.
Swartpuntia (frondlike metazoans) and Ernietta (ribbed saclike metazoans) are part of the Ediacaran fauna.

Recently, in 2004, a new geological period, the Ediacaran, was formally added to the time scale. It immediately precedes the Cambrian period, and therefore lies within the Proterozoic.
They became prevalent during the Ediacaran, 635 to 542 million years ago.
noun
