fossils are marine fossils. Brachiopods are among the most common fossils in Indiana rocks. They resemble clams, but are a distinct type of marine animal. Bryozoans live together in colonies and form branching stemlike, lacy, or encrusting forms. A single zooid is hardly bigger than a comma on a printed page.Bryozoans Bryozoans are colonies of tiny filter-feeding animals. The colonies can take many forms. Prasopora forms a lens-shaped colony over a brachiopod shell. Atactoporella covers small snails. Others form tree- or frond-like, free-standing colonies.

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.Phylum Bryozoa – Bryozoa are tiny filter-feeding colonial organisms which build a calcium carbonate structure which have varied appearances (lacy fans, corkscrews, and twig-like shapes are common).

Bryozoa are not plants. Some of the preserved stony skeletons of Cincinnatian bryozoa are branching colonies resembling twigs of a tree. Bryozoa are animals, not plants. At the time in earth history when the Cincinnatian sediments were laid down, between 451,000,000 and 443,000,000 years ago, no advanced vascular plants existed on the earth.Description. Conopeum reticulum colonies form extensive gauze-like encrustations. Individuals (zooids) within the colony are approximately 0.4-0.6 x 0.2-0.3 mm in size, elongate, rectangular or polygonal in outline with a thickened, finely granular margin. The margin occasionally bears a few thin, pointed, delicate spines.Fossils are important in understanding the history of the world because they provide physical evidence of animals and plants that lived in the past. Through their discovery, paleontologists uncover new ideas about former life on earth.Experts from Durham University in the UK and Yunnan University and Guizhou University in China conducted research and discovered that the fossils, previously believed to be the oldest Bryozoans, are actually green algae.
