Has the KCET series "Primeval" got you wondering about the giant dinosaurs that walked the earth before we humans took over? If you're curious about the real-life primeval, you should check out KCET's new series of educational shorts, "More." In this first run of "More," we sent a crew to the Natural History Museum of Los Angeles to talk to an expert, Luis Chiappe, director of the museum's Dinosaur Institute.
