Description: | This irregular rounded fossil is a colonial coral (a group of corals living together) that has grown on a sea snail's shell. A close look reveals that the colony is made up of hundreds of individual corallites (the hard tube-like skeletons) which protected the soft body of the polyp (the actual coral animal). The coral polyp fed by catching food particles in its tentacles. Alcyonidium usually lived in warm shallow water gravel communities that are dominated by bivalves and gastropods, in 10 to 15m deep water. | License: | http://www.imagine.org.uk/about/copyright/ | Rights holder: | Tyne & Wear Museums | Subjects: | fossils natural world | Source: | Tyne and Wear Imagine | Identifier: | http://www.imagine.org.uk/details/index.... | Go to resource |
