In most cases you may not be able to identify your fossil more specifically than as a bryozoan. Bryozoans were able to live almost anywhere: on a brachiopod shell, the side of a cephalopod, coating sea plants, or in an individual colony on the sea floor. We use bryozoan (phylactolaemate, ctenostome, and cyclostome) and bilaterian out-groups and 18 fossil calibration points and present a time-calibrated bryozoan tree, asking how much of the early lineage leading to extant cheilostomes is now "invisible" (i.e., not detected) in the fossil record and when Bryozoa might have originated.You too can become a part of this amazing team and work with fossils that are millions of years old.

Using the pictures below, find the closest match to your fossil.Bryozoans are very small, colonial animals. In mass, they combine to form mats, mounds, branches, fans, or lacy fronds. Tentacles surrounding their mouths grabbed microscopic organisms floating in the water. These animals differ from coral in that they lived in pits on the surface of the structure and not in radiating partitioned cups.Bryozoan. Bryozoans (from the ancient Greek for “moss animals”) are so named because some living bryozoan colonies resemble mosses. Not to be confused with plants, bryozoans are invertebrate animals with a long fossil record, from the Early Ordovician Period to the present.
