Giant sharks once swam the seas that covered what's now eastern Idaho, and scientists have new proof: A spiral-shaped array of fossilized shark teeth was uncovered by a mining crew in a heap of deposits near Soda Springs. The teeth were identified as those of a prehistoric shark called Helicoprion that swam the area 250 to 270 million years ago, before the Bonneville Flood, the Idaho State Journal reports. Phosphate deposits in southeastern Idaho are believed to have preserved the pristine fossil specimen, which includes the lower jaw cartilage, teeth and rare impressions of skin.
