Collected from the Sunshine state, coral is the outside skeleton of tiny ocean animals called polyps, which live in colonies attached to hard underwater surfaces. Agatized coral occurs when silica in the ocean water hardens, replacing the limy corals with a form of quartz known as chalcedony. This long process (20-30 million years) results in the formation of a “pseudomorph,” meaning that one mineral has replaced another without having lost its original form.

These tracks are found in rock from the Devonian Era, 414 to 390 million years old. They were formed by trilobites as they were walking or striding across muddy flats. When a trilobite is up to speed and really cruising along and striding quickly on the surface, the endopodites (feet) leave paired leg marks called Diplichnites.
