on Sunday Morning Magazine: Dr. Nazir Ibrahim is a world-renowned paleontologist who teaches at the University of Detroit-Mercy, and leads expeditions to Africa's Sahara (and discovering a new dinosaur--spinosaurus). He's preparing for a new expedition scouting for a longer one in the fall. More discoveries are buried in that sand. Dr. Ibrahim is a natural and engaging teacher, and directs us to a couple of new dinosaur books: 1000 Facts about Dinosaurs, Fossils, and Prehistoric LIfe, and Weird but True! Dinosaurs.
