Rugose coral.

Here, we report the first measurements of nitrogen isotope ratios of coral-bound organic matter (CB-δ15N) in samples from Mid-Devonian reefs (Givetian, ca. 385 Ma), which represent the oldest isotopic constraint on the evolution of photosymbiosis to date.

All horn corals live in a cup called a calyx (KAY-licks). The calyx often has radially alligned ridges or grooves, which are called septa. These septa were the skeletal support plates for the coral animal or polyp.Corals are formed by small animals, the polyps of the phylum Cnidaria.They are marine, either on continental shelves or round oceanic islands. They live in colonies.. All the polyps in a colony are zooids: they are all clones, genetically identical.Colonies of the same species release gametes together, over one, two or three nights around a full …

Abstract. Rugose corals are one of the major fossil groups in shallow-water environments. They played an important role in dividing and correlating Carboniferous strata during the last century, when regional biostratigraphic schemes were established, and may be useful for long-distance correlation.
