Heliophyllum is an extinct genus of corals that existed predominantly in the Devonian. Heliophyllum is of the order Rugosa and can be referred to as horn corals. ^{[1] [2]} They were mostly solitary animals, although some were colonial. ^[1] The genus had a wide distribution. Fossils of H. halli have been found in the fossil rich Floresta Formation of the Altiplano Cundiboyacense, Colombia. ^[3] This genus used its nematocysts to stun prey.
