I dimly recall that in... oh... 4th or 5th grade, perhaps, we made paper mache dinosaurs. A classmate & I made a Spinosaurus. I don't think we even knew what it was called back then. We just thought the spine was cool. So I'll say Spinosaurus. (By the way, I read that Spinosaurus was larger than t-rex or giganotosaurus. It was thought to spend much of it's time in the water & it was apparently primarily a fish eater.)
