Description
This exceptional Millepora Fire Coral fossil originates from the Cretaceous period and was discovered at Cow Gap, Sussex, UK. This fossil dates back approximately 100 million years and represents the preserved hard skeleton of a once-thriving shallow marine reef organism.
Millepora, commonly known as fire corals, are hydrozoans—not true corals—but resemble stony corals due to their calcareous exoskeletons. These fossils capture the complex, net-like or porous surface texture typical of Milleporids, which were important contributors to reef-building in ancient seas.
