Discussion:

This small encrusting organism grew and lived entirely as an
encruster on other skeletons. The ends of each branch have a small
opening for the animal that produced the branch, but openings are
limited to the ends of the branches. The tubes of each branch are
solid. Because of its small size and encrusting habit, this fossil
is placed with the cyclostome bryozoans (Condra & Elias, 1944).
A Permian example of Hederella is reported from the Ural Mountains
in Bashkortostan (Lisitsyn, 1998).
