Bryozoan fossil identification.
Back in 2021, Protomelission gatehousei was named the oldest bryozoan, a member of a group of colonial organisms made up of tiny animals known as zooids. The fossils were around 40 million years older than any previously discovered, dating it to the Cambrian period when other major animal groups are thought to have first evolved.
Fenestella (bryozoan) Fenestella. (bryozoan) Fenestella is a genus of bryozoans or moss animals, forming fan–shaped colonies with a netted appearance.

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 Fossils Bryozoans, or moss animals, are colonial invertebrates. They are probably the most common fossil at Caesar Creek. They look similar to corals, but are not the same. A bryoza colony contains hundreds of individual polyps called zooids. Each zooid is less than a millimeter across.Freshwater and brackish species of bryozoans belong to the Phylactolaemata and Gymnolaemata class. Twelve species of bryozoans were recorded and morphologically determined at eight locations in the Black Sea and the Adriatic basin in Croatia.

They are the most abundant fossils in many limestones, calcareous shales, and mudstones. At least 3,500 living species and 15,000 fossil species are known. Bryozoans are small animals (just large enough to be seen with the naked eye) that live exclusively in colonies. The lack of body fossils of unmineralized bryozoan fossils in the Cambrian fossil record seems surprising given the increasing number of Lagerstätten available. It is worth noting, however, that soft-bodied bryozoans are also conspicuously absent from the Lagerstätten within the known stratigraphical range of the phylum.
