Scientists have Watch Fast & Furious 8 Onlinenamed a new species of shark that likely stalked the Atlantic and Pacific coastlines some 20 million years ago.
Megalolamna paradoxodon, now extinct, had left few clues of its long-ago existence.
Researchers found just five of the species' mega-sized teeth at sites in Japan, California, Peru and North Carolina, according to a study published this week in the journal Historical Biology.
The chompers measured nearly 2 inches long, suggesting the shark could have grown to be up to 12 feet long. The great white shark, by comparison, can reach lengths of up to 20 feet.

The species name, paradoxodon, combines the Latin word "paradoxum," or paradox, with the Greek word "odon," or teeth.
The sharks likely lived in shallow coastal waters in the mid-latitudes and feasted on prey such as medium-sized fish, researchers said.

"However, the fossil teeth are too robust for Lamna-- it shows a mosaic of dental features reminiscent of the genus Otodus," Shimada told Live Science.
"So, we determined it to be a species new to science that belongs to the family Otodontidae, with no direct relationship with Lamna," he told the science news site.
