You make a compelling case in certain ways and I will need to research further to argue against it but at this stage I believe in dinosaurs.
A question: doesn't the fact that fakery keeps getting pointed out by those in the field themselves imply there must be real dinosaurs? In the virology world they all go along with viruses they're not saying, "Hey that's a real virus but that one's not," or at least not AFAIK. How can there only be fake dinosaurs if so much fakery is called out? What makes something "fake accepted as real" and another "fake recognised as fake"?
The dinosaur world reminds me of the art world - loads of shenanigans. The thing is despite the fakery in the art world we still accept that there is art created by the artists said to have created the art, we know it's not ALL fake, that would make no sense. I think the same applies to dinosaurs.
I think what emerges is that there are hoaxes within the dinosaur world - gobsmacking ones - but dinosaurs as a phenomenon are not a hoax.
