Corals are marine invertebrates that typically live in compact colonies of many identical individual polyps. Coral as a group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. Coral is essential for maintaining these highly diverse ecosystems, which have been known as the 'rainforests of the sea.' Some coral reefs, however, are rapidly disappearing due to the effects of global warming and lukewarm commitment to effecting environmnetal change from nations around the world. Preserve a piece of ecological history with this specimen of polished fossil coral. The surface of the fossil is highly detailed, and individual polyps can be easily identified. The specimen is large enough to serve as a paperweight (4"x4"x2"), and makes for a great sample to be passed around in biology classrooms. Makes a great gift for the fossil collector in your family!
Note: Please be aware that this is a natural fossil and as such each piece is one of a kind! The one you receive may not be exactly the same as the ones pictured but it will be similar. Price is per each piece. They come in irregular shapes, sizes and weights.
