Re: Stegosaurus with protofeathers? Absolutely!



How many non-bird diapsid with protofeather-like integumentary
structure was found outside China?<<<

Wasn't Shuvuuia found in Mongolia? Integumentary structures have been reported on it as well. And while it's a matter of nomenclatural debate, I'd add Archaeopteryx to the list of non-bird diapsids found outside of China with preserved integumentary structures.

But honestly, I'm not sure I agree with the implicit point, that there is something fishy about the epidermal structures because they are all coming from a series of Chinese LagerstÃtten. How many other terrestrial or near-terrestrial Mesozoic LagerstÃtten are known?

To look at it another way, let's rephrase the question: "How many Mesozoic mammals are known from outside of China that preserve integumentary structures?"
