The bryozoan had bushy colonies with branches that became thickened by the continuous budding of new, blister-like zooids. As they did so, corals that had settled on the surface of the bryozoan became ever more deeply embedded, while maintaining an opening on the surface by growing at the same rate as the host bryozoan.Some encrusting bryozoan colonies with mineralized exoskeletons look very like small corals.
