Physical properties

Formation & geological history

Coral skeletons accumulated in ancient marine environments and were later buried and fossilized, often through mineral replacement; the specimen’s age is unknown.

Uses & applications

Primarily collected or used decoratively; fossil coral is sometimes cut and polished for jewelry.

Geological facts

Fossil coral may preserve the corallites—the individual chambers that housed coral polyps.

Field identification & locations

The honeycomb-like repeated pores support a coral identification, but image detail is insufficient to distinguish fossil coral from a porous mineral specimen. Fossil corals occur in sedimentary rocks worldwide.
