Corals. Corals are cnidarians that live as polyps attached to the sea floor. Polyps of modern stony (scleractinian) corals produce a hard skeleton that is easily fossilized. Extinct rugose and tabulate corals also had hard skeletons and are commonly found as fossils. The scleractinian corals are probably descendants of the rugose corals.
