I was a real dinosaur fan when I was a kid. but to my dismay there were all these dinosaurs popping out everywhere. I couldn't keep track.
Looks like the juveniles are very different from adult same species; and they don't deserve another name.
Hooray for Jack Horner and making sense of the whole thing. Hooray for my childhood favorite triceratops.
