570 vanished lives

161Precambrian

Its flat oval body moved across microbial mats like a rhythmically quilted cushion, leaving feeding traces behind.

162Precambrian

A horseshoe-shaped front led a body of offset leaflike units, giving it the appearance of a flattened soft worm.

163Precambrian

A featherlike body of repeating branches was anchored by a disc in deep water, yet it had neither chlorophyll nor a mouth.

164Precambrian

Its low oval body crawled across microbial mats while a front feeding structure left fan-shaped sets of scratches.

201Precambrian

Rows of quilted sacks lived half-buried in sand, forming one of the Ediacaran seafloor's strangest communities.

202Precambrian

Six branching vanes surrounded a central axis, making the organism resemble a soft pine cone standing on the seabed.

203Precambrian

Three curving spiral arms created a body symmetry almost absent among living animals.

301Precambrian

Its quilted branches lay flat rather than rising from a stem.

302Precambrian

Dense stands of narrow tubes formed one of the earliest large colonial scenes.

303Precambrian

Bead-like discs arranged in strings may record an early macroscopic colony.
