It was obvious. You'd have to be blind not to recognize it. I certainly didn't write scientific papers in high school.

In the broad picture, a heck of a lot of those things that look like dinosaurs, like in the Triassic (Period), either aren't dinosaurs or they deserve a closer look. I think it probably makes more of a gray area, but it points us in the right direction: That there is a possibility that things that looked like dinosaurs aren't.
