Another short video clip of a large agatized, fossil coral “geode” from Florida filled with druzy quartz. This fossil coral is Miocene (25-32 million years) in age, and was formed when fine sediments covered shallow coral reefs. As silica rich groundwater through the rock that was formed (and exposed as sea-levels dropped), it replaced the calcium carbonate skeleton of the coral with Chalcedony.
