Summary: | Rugose Corals, often referred to as Horn Coral, are an extinct order of stony corals in the phylum Cnidaria . They lived from the Ordivician period to the end of the Permian period, and can be found worldwide. A new fossil of Siphonophrentis gigantea , a species of Rugosa in the family Streptelasmatidae , has been recovered from the Devonian strata of the Lucas Formation. The fossil gives clues towards the paleobiology of Siphonophrentis , revealing it to have likely anchored itself to the sea bed in the ocean depths. Siphonophrentis gigantea likely had no relationship with Zooxanthellae , a kind of Dinoflagellate that gives modern extant coral their colour and allows them to photosynthesize. These single celled organisms appear to be absent in Siphonophrentis , and it instead received nutrients from a rich amount of biological debris that fell into its habitat. Further comparisons can be made between Siphonophrentis and the extant, cold-water coral Lophelia pertusa. |
