Finally, while size records aren't supposed to be high on paleontologists' agenda, the immensity of C. saharicus does bear on dinosaur evolution, especially when it's put into context. Last fall paleontologists working in South America found a similarly huge carnivore, called Giganotosaurus, that was said to be a little larger than T. rex (in fact, the sizes of all three giants probably overlapped). "What's interesting," observes Norell, "is that everywhere you go in the world you have these truly enormous carnivorous dinosaurs that were much larger than any terrestrial carnivores since." One implication, says Sereno: "I think...
Scientists are finding lots of surprises. The facial bones and teeth of the tyrannosaur-topping dinosaur, it turns out, are the same as those of a rare species, called Carcharodontosaurus saharicus ("shark-toothed reptile from the Sahara"), which were found in Egypt in the 1920s but destroyed during World War II. The new skull not only establishes the animal's size but also proves that the huge dinosaur had a comparably huge home range that spanned all of North Africa...
