The Bryozoa, also known as Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals that resemble corals. They are found in marine, brackish and freshwater habitats. Marine species are common on coral reefs but a few occur in oceanic trenches, and others are found in polar waters.. Pyrosomes, genus Pyrosoma, are free-floating colonial tunicates that usually live in the upper layers of the open ocean in warm seas, although some may be found at greater depths.

Unit D, which caps the Pungo River sequence, is slightly phosphatic, sandy, bioclastic-rich dolosilt. Fossil fragments are largely barnacles and bryozoans. All four units occur in the eastern portion of the Aurora district, but only A and B are present to the west near the updip limit of the formation. Pyrosomes, genus Pyrosoma, are free-floating colonial tunic

Bryozoans are all aquatic animals, and most are marine, except for the freshwater forms classified in the Phylactolaemata. In aquatic habitats, bryozoans may be found on all types of hard substrates: sand grains, rocks, shells, wood, and blades of kelps and other algae may be heavily encrusted with bryozoans.
