Fossilized skeleton of Archimedes Bryozoan Fossils of about 15,000 bryozoan species have been found. Bryozoans are among the three dominant groups of Paleozoic fossils. [ 70 ]
Archimedes is a genus of fenestrate bryozoans with a calcified skeleton of a delicate spiral-shaped mesh that was thickened near the axis into a massive corkscrew-shaped central structure. The most common remains are fragments of the mesh that are detached from the central structure, and these may not be identified other than by association ...
Fenestellidae is a family of bryozoans belonging to the order Fenestrida. The skeleton of its colonies consists of stiff branches that are interconnected by narrower crossbars (or dissepiments). The individuals of the colony (or zooids) inhabit one side of the branches in two parallel rows or two at the branch base and three or more rows ...
The skeleton of Fenestella colonies consists of stiff branches that are interconnected by narrower crossbars (or dissepiments). Between two and eight individuals of the colony inhabit each of the opposing front sides of the approximately rectangular openings between the branches (or fenestule) in one row, and the void they left when they died can be recognized as two rows of small rimmed pores ...
Among cyclostome bryozoans, the calcitic skeleton is usually lamellar, consisting of tabular or lath-like crystallites stacked like tiles at a low angle to the wall surface. Cheilostome bryozoans may exhibit a similar ultrastructure but more commonly have fibrous skeletons consisting of needle-like or bladed crystallites oriented almost ...
Phylactolaemata [1] is a class of the phylum Bryozoa whose members live only in freshwater environments. Like all bryozoans, they filter feed by means of an extensible "crown" of ciliated tentacles called a lophophore, and like nearly all bryozoans (the only known exception being Monobryozoon), they live in colonies, each of which consists of clones of the founding member.
Here's what to know about the bryozoan in Ohio. It could actually a colony of small animals. Meet the bryozoan, the mysterious, microscopic animal living in Ohio's bodies of water
Lichenalia belongs to the class Stenolaemata within the phylum Bryozoa. The genus is classified in the family Rhinoporidae, which is characterized by a vesicular skeleton with tunnels that appear as ridges on the surface of the colony. Other genera in the Rhinoporidae include Rhinopora, Fistulipora, and Heterotrypa.
