Originally interpreted as a hexactinellid sponge,[1] the organism also bears some coelomate characteristics, including bilateral symmetry.
[2][3] The organisms take the form of a rounded, dome-like bag, 7–68 mm in diameter, with an uneven margin.
A stalk emerges from the central point of some specimens, at the top of the organism; in life, it probably extended into the water column.
[1][4] The organisms have been interpreted as tall suspension feeders, reaching 10 cm or more up into the sea water above them.
[1] First found in the Pound group of Australia, fossils have also been recovered from the White Sea region of Russia.
