Why you should listen
Paleontologist Nizar Ibrahim, a postdoc at the University of Chicago, wanted to uncover 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. “The entire skeleton has water-loving river monster written all over it,” he says.
Ibrahim is a TED Fellow and a National Geographic Emerging Explorer.
