Orbisiana is an Ediacaran benthic organism formed out of series of agglutinated spherical or hemispherical chambers.

Orbisiana occur in aggregates made up of rows arranged in sometimes branching chains.

[1] 3-D analysis has shown Orbisiana to be cylindrical in shape and open at both the top and bottom ends of its structure.

[8] Over 100 specimens have been collected from the lower Ediacaran Lantian Formation located in Xiuning and Yixian counties of the Anhui Province, China.

[3][6] Orbisiana likely favored calm and well aerated shallow marine habitats in which it could utilize sunlight for benthic photosynthesis.
