Georgia designated the shark tooth as the official state fossil in 1976. A fairly common fossil on the Georgia coastal plain, the fossilized shark tooth is prized by collectors. These prehistoric shark teeth are found in a range of colors - most common are black or gray, less common are the white, brown, blue, and reddish-brown teeth.
Many types of sharks lived in prehistoric Georgia - the oldest teeth date back about 375 million years. One of the largest extinct species of shark tooth was Otodontidae Carcharocles megalodon (whose fossilized teeth are pictured here).
