I think there's a time in every child's life where they want, at least briefly, to be a paleontologist that studies dinosaurs. I certainly went through my dinosaur phase. I think of Tyrannosaurus rex as the most mainstream of dinosaurs. T-rex is instantly recognized and likable (maybe because Dromiceiomimus brevitertius just doesn't have the same ring to it.)

Hundreds of tiny dinosaurs were laser cut from cardboard salvaged from recycling bins. These dinosaurs are composed of 4 parts: two arms, a head torso, and an arm torso. Dinosaurs were given away with instructions to put them together and either keep them or disperse in a location of the participant’s choosing. If you want to make your own, I made a tutorial on Instructables.
