Heliolites is a large and heterogenous[1] genus of extinct tabulate corals in the family Heliolitidae.[2] Specimens have been found in Ordovician[3] to Devonian[4] beds in North America,[5] Europe,[4] Africa,[6] Asia,[7] and Australia.[3] The genus is particularly abundant in the Wellin Member of the Hanonet Formation of Belgium.[8]

Members of the genus are distinguished by a prominent tubular coenenchyme (the tissue linking neighboring polyps) with 14–17 tubules around each corallite (the stony cup in which each polyp sits.)[9]
