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.

Further, they show partitioning of new individuals from parent tubes through the formation of a separate wall, a characteristic of interzooecial budding in bryozoans.

Zooids can take several forms, but the most common forms in each class are autozooids, which function in feeding the colony and excreting waste. Branching bryozoans may look similar to branching corals, but the zooids in bryozoa do not have septa or a columella as corallites do in corals.

The Bryozoa are the only animal phylum with an extensive fossil record that does not appear in Cambrian or late Precambrian rocks.
