Photo: Massive New Meat-Eating Dino Had "Steak Knife" Teeth



A 95-million-year-old fossil jawbone (top) displays some of the banana-size "steak knife" teeth belonging to a new species of dinosaur dubbed Carcharodontosaurus iguidensis.

At about 45 feet (14 meters) long, the species is among the largest meat-eating dinos that ever lived—taller than a double-decker bus, as seen in an artist's conception (bottom).
