Well if Dave says it, then it must be true, right? I might as well delete

the comparable dinosaur authority? Holtz? Bakker? Sereno?

I believe that HP Paul was referring to a specific paper by HP Unwin, not specifically making an appeal to authority. He did not at any point infer that HP Unwin was the pterosaur authority or that yours or anyone else's work was inferior or superior. Nor did it seem that HP Paul was implying that authority is superior to evidence. I'm certain that no insult or offense was intended, nor do I see insult or offense in HP Paul's message.
