Description

Corals in this genus are solitary, erect and flattened, with a short, thick peduncle and a long elliptical, slightly curved calyx. The costae are indistinct, simple and flat. The septa are in five complete cycles and are narrow, closely packed, slightly sinuous, and covered with projecting granules.[3]

Fossil record

Fossils of Flabellum are found in marine strata from the Cretaceous until the Quaternary (age range: from 66.043 to 0.012 million years ago.). Fossils are known from various localities in Europe, North America and Australia.[1]
