Ediacaria is a

Baikalian age (850–650 Ma) of the Upper Riphean[3] to 501 million years ago, well into the Cambrian
Period. Ediacaria consists of concentric rough circles, radial lines between the circles and a central dome, with a diameter from 1 to 70 cm.

Systematics and taxonomy

Ediacaria was named by

Late Cambrian deposit at Booley Bay (County Wexford), Ireland. The species were named after the Flinders Ranges
and Booley Bay, respectively.

Ediacaria is possibly a synonym for

form taxon, Ediacaria may yet be valid and denote one specific genus among several that seem to make up Aspidella. Spriggia wadea
is quite likely a synonym of Ediacaria (and consequently, possibly Aspidella); the differences seem to be merely due to different substrate in which the animals were embedded. (Gehling et al. 2000)

Ediacaria was often classified as a jellyfish (a Scyphozoan Cnidarian), and has also been interpreted in many of the categories postulated to house the Ediacaran biota. A conspicuous filamentous microstructure preserved in some pyritised specimens suggests that it may have been a microbial colony, which disrupted the surrounding microbial mat to create the distinctive pattern (Grazhdankin, in press).
