It's not like I'm stubbornly trying to disagree with you, but think of it this way: Sharks and dolphins have similar body shapes and similar lifestyles, because they share similar ecological niches. Maybe Aptonoth and Parasaurolophus have a similar situation - they play the same roles in their environments, and therefore look similar, despite not being related. It's called "convergent evolution", or something like that.

I'm not saying you're wrong, I'm just clarifying my opinion. In fact, it's totally possible that everything in Monster Hunter evolved from the very prehistoric creatures that went extinct in the real world.
