Blueflower formation from the Mackenzie Mountains of Northwest Canada. In 2008 a similar Ediacaran was discovered from the late Ediacaran Khatyspyt formation of Northern Siberia by Dmitriy V. Grazhdankin, Uwe Balthasar, Konstantin E. Nagovitsin, and Boris B. Kochnev. Carbone et

is a genus of the
Ediacaran biota (635–542 Ma) found in Northwest Canada, and Northern Siberia. It has been found in both shallow water and deep-water assemblages no older than 560 Ma placing it within the youngest Ediacaran.
