He he he. Things are always changing. It seems the scientists and paleontologists or whoever studies dinosaurs can never get their facts straight on how the dinosaurs really lived. They keep changing their information, and discoveries like this, I'm sure, only cause further change. You know, stuff like how the T-Rex walked, or even changing certain species of dinosaurs from leaf-eater to meat-eater (I heard about this in another topic on this board, too) class. Their information is never the same. Will they ever know exactly how they lived? Probably not in a million years [pardon the terrible pun].
