Leptomitus
''Leptomitus'' is a genus of demosponge known from the Middle Cambrian The Cambrian Period ( ; sometimes symbolized C with bar, Ꞓ) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon. The Cambrian lasted 53.4 million years from the end of the preceding Ediacaran Period 538.8 million ... Burgess Shale. Its name is derived from the Greek ''lept'' ("slender") and ''mitos'' ("thread"), referring to the overall shape of the sponge. 138 specimens of ''Leptomitus'' are known from the Greater Phyllopod bed, where they comprise 0.26% of the community.

Hazelia
''Hazelia'' is a genus of spicular Cambrian demosponge known from the Burgess Shale, the Marjum formation The Marjum Formation is a Cambrian geological formation that overlies the Wheeler Shale in the House Range, Utah. It is known for its occasional preservation of soft-bodied tissue, and is slightly younger than the Burgess Shale The Burgess S ... of Utah, and possibly Chengjiang. It was described by Charles Walcott in 1920. Its tracts are mainly radial and anastomose to form an irregular skeleton. Its oxeas form a fine net in the skin of the sponge.

Choia
''Choia'' is a genus of extinct demosponge ranging from the Cambrian until the Lower Ordovician periods. Fossils of ''Choia'' have been found in the Burgess Shale in British Columbia; the Maotianshan shales of China; the Wheeler Shale in Utah; and the Lower Ordovician Fezouata formation. It was first described in 1920 by Charles Doolittle Walcott. Life habit ''Choia'' was originally thought to be not attached to the sea bed: the living animal was originally thought to rest directly on the substrate, with the radiating spines from the edge of its flattish, conical body, giving an appearance not unlike that of the peak of a big top, with guy lines. Recently discovered fossils from Lower Ordovician Morocco show that the living animal was actually suspended high above the seafloor, attached via stalk-like spines derived from spicules. Water is assumed to have entered the sponge parallel to the spines, being expelled, presumably, from a central opening. Species reached up to ...
