How common are coral fossils?

Coral fossils are generally considered to be relatively common. Corals have been around for hundreds of millions of years, and they have left behind a significant fossil record. While it may not be as abundant as some other types of fossils, such as shells or bones, coral fossils can still be found in various locations worldwide. The abundance of coral fossils can vary depending on the geological and environmental conditions of a particular area. For example, areas that were once covered by seas or shallow oceans with thriving coral reefs are more likely to have a higher concentration of coral fossils. Additionally, certain time periods, such as the Paleozoic era, are known for their extensive coral reef formations, which further contribute to the availability of coral fossils. Overall, while individual finds can be considered rare or unique, coral fossils are generally not considered rare in the broader context of fossilization.
