Bryozoans characteristics
Bryozoans. Bryozoans are colonial invertebrates, many of which build elaborate skeletons of calcium carbonate. Bryozoans are common in today’s oceans, where they are frequently found encrusting rocks or shells. During the Paleozoic era, however, bryozoans commonly grew off of the sea floor as erect structures. After they died, their skeletons ...Bryozoans and Corals are aquatic invertebrates that belong to phylum Bryozoa and phylum Cnidaria, respectively. Bryozoans are advanced corals.

In almost all cases an egg-shaped fossil is something else. Most fossil "eggs" are weathered and rounded rocks, rather than fossils. siderite nodules and concretion s can have smooth, oval shapes and may appear like eggs. Other rocks may be rounded in streams into oval shapes.Lab #3: Brachiopods and Bryozoans. Identify a fossil as an articulate brachiopod, inarticulate brachiopod, or bryozoan. Be able to determine the order of an articulate brachiopod using the chart below. Know the skeletal structure and material of each of these animals.
