journal = Geobios]The chancellorids were sessile, bag-shaped and radially-symmetric organisms. Their fossils show no trace of a gut or other organs, supporting their interpretation as a
sponge . Like those of the Halkieriids, their sclerites have an internal "pulp cavity" and a thin external organic layer; the walls are made ofaragonite ; the aragonite fibers run mainly from base to tip, with each being closer to the surface at the end nearest the tip.ee also
