Explorer shares the secrets of mystery dinosaur

Paleontologist and National Geographic Explorer Nizar Ibrahim met Friday with students at McCarty Elementary School in Aurora to share the story of how he uncovered the mystery of the Spinosaurus, a gigantic predatory dinosaur whose only known remains were lost during World War II.

After identifying a new skeleton at a dig in North Africa, Ibrahim made the landmark conclusion that the Spinosaurus may have been the largest carnivorous dinosaur to ever live.

Its crocodile-like head, dense bones, short legs, and wide, paddle feet suggest it was a water dweller unlike any other.
