Generally speaking, a fossil is any evidence of past plant or animal life that is preserved in the material of the Earth's crust....Bryozoans (Ordovician to today with no peak period) are animals that live in a colony and excrete a skeleton to support themselves. Sometimes the skeleton is made of minerals, and sometimes it is made of chitin. Bryozoans are primarily marine, but are sometimes found in tidal or delta environments. Each animal in the colony is called a zooid.The oldest fossils previously confirmed to be bryozoans are from the earliest part of the Ordovician, during the time interval called the Tremadocian stage (485.4 million to 477.7 million years ...species of bryozoan (fossil) edit.

Bryozoans, also known as Ectoprocta, and commonly referred to as moss animals (bryophytes are mosses) have been around since the Cambrian. Most bryozoans are marine creatures, but one class lives in freshwater. These are small, sessile, colonial invertebrates that have calcium-based skeletons (like corals).

Moss animal, any member of the phylum Bryozoa (also called Polyzoa or Ectoprocta), in which there are about 5,000 extant species. Another 15,000 species are known only from fossils. As with brachiopods and …Fossil corals typically form cup-shaped or cylindrical skeletons that are usually composed of aragonite. By contrast, bryozoan colonies consist of microscopic, calcified zooids that form flat, branching colonies. Bryozoans usually do not form individual cups, tubes, or other shapes like fossil corals do.Ancient fossil may be the first bryozoan with a hard skeleton. A colonial animal which was among the first to develop an exoskeleton may have been discovered. Fossils which could represent the earliest known hard-bodied bryozoan were discovered in Nevada, USA, pushing back their evolution by over 10 million years.The Bryozoans act as a perfect pioneer species for secondary succession. As all pioneer species, bryozoans are resilient organisms that are small, simple, and capable of colonising in a hostile environment, altering and creating less stressful conditions for a more complex successional species as in facilitative successions (Bruno et al., 2003).The bryozoans are little known but common group of organisms, which occur abundantly as fossils and in modern seas. The phylum Bryozoa comprises approximately 4,000 living and 15,000 fossil species. They live in colonies containing several microscopic individuals but colonies may range in size from a few mm to about 10 cm in diameter.Bryozoans are some of the most abundant fossils in the world. They are also widespread today, both in marine and freshwater environments, living at all latitudes and at depths ranging downward to at least 27,900 feet (8,500 meters).

The colonies of different species take different forms, building exoskeletons (outer protective structures) similar to those of corals. Most colonies are attached to a structure such as a rock or submerged branch. Freshwater bryozoans' exoskeletons are gelatinous (like jelly) or chitinous (like the "shells" of insects ...Fossils are important in understanding the history of the world because they provide physical evidence of animals and plants that lived in the past.

Bryozoans are generally sessile (attached to substrata) colonial invertebrates that use ciliated tentacles to capture suspended food particles. This group is primarily marine, with more than 4,000 species worldwide, about 50 of which are freshwater species ( Pennak, 1978 ). Bryozoans (sometimes referred to as Entoprocta and Ectoprocta) are microscopic sea animals that live in colonial structures that are much larger than the individual animal. Because these structures are usually composed of secreted calcite, they commonly form fossils.Fossils are the traces or remains of organisms buried and preserved in sediments. They consist not only of hard body parts, such as bone and shell, but also may be impressions of plants, or tracks, trails, and burrows. Fossils can tell us what life was like on Earth in ancient geologic time, helping geologists describe ancient depositional environments and …The origin of Bryozoa has long been an intriguing mystery, largely due to the dearth of unambiguous bryozoan fossils within Cambrian strata1-5. Recently reported earliest bryozoan Protomelission 2, an early Cambrian phosphatized microfossil from Australia and China, was subsequently contested and proposed as calcified dasyclad algae1.
