Fossilized coral shows us what coral reefs looked like millions of years ago! They are made from tiny animals that lived in the sea.
The Fossilized Coral has a stony, often grey or brownish appearance, sometimes with hints of red or yellow from mineral replacement. It distinctly shows preserved internal structures like radiating septa or honeycomb-like patterns, clearly differentiating it from ordinary rocks.
