Agatized Fossil Coral is Florida's state stone. The species of coral for the state stone is Montastrea. However, many types of coral species make-up this colorful coral.

They are found in ancient ocean beds, where silica rich groundwater has percolated through them and over time has replaced it's calcium carbonate skeleton with a hard variety of Chalcedony. This leaves the ornamental fossil with a sometimes banded stone look.

It is about 38-25 million years old and from the Oligocene-Miocene period. These fossils are found in a variety of colors- white, gray, brown, black, yellow and red. Different trace minerals in the agate create these colors.

Much of these fossils have been found in the Tampa Bay area, near Ballast Point. However, more have been found, recently, in North Florida in Madison County, Florida.

These excellent prehistoric fossils are sought after by collectors of all types.
