A living fossil, sea turtles still nest up and down the busy and overbuilt South Florida coast and travel past our shores throughout the year. The various species of ocean roaming turtle are approximately 200-300 million years old but because they lay their eggs on our beaches, scientists are able to closely study the nomadic animals. For this reason, and with modern techniques such as satellite tagging, we can occasionally glimpse closely into their mysterious lives.
Tucked away on a high shelf in the collections room of the Museum of Science is a startlingly unique rock specimen. It is white with long jutting crystal arms and made of a fragile mineral called calcite. The piece looks like it comes from completely different planet.
