Ediacaria
Sign in to saveEdiacaria is a nomen dubium fossil genus dating to the Ediacaran Period of the Neoproterozoic Era. Unlike most Ediacaran biota, which disappeared almost entirely from the fossil record at the end of the Period, Ediacaria fossils have been found dating from the Baikalian age (850–650 Ma) of the Upper Riphean 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 Reg Sprigg in 1947, after the Ediacara Hills in South Australia. Two species are recognised: E. flindersi, described by Sprigg from the Pound Quartzite in the Ediacara Hills, and E. booleyi, described in 1995 from a Late Cambrian deposit at Booley Bay (County Wexford), Ireland. The species were named after the Flinders Ranges and Booley Bay, respectively.
