That's nicely said, but it strawmans my views.

That's right, ultimately we have only stories at our disposal. That's the postmodern side of my philosophy. But I don't think all stories are equally great. The exoteric, sentimental religious story is the one I'm targeting with this dinosaur argument. That argument emphasizes the horrific side of nature that's left out of sentimental theology.

I agree that I'm only generalizing about millions and millions of years of dinosaurian complexity and variety. But the point is that, however you want to characterize the dinosaurian eon, there's no chance that God, as pictured in the sentimental mainstream religions, would have created that eon. There's an obvious mismatch between the cosmicist upshot of deep time, and the smallness of our religions' conceptions of ultimate reality.

So there are bad stories and there are better ones. The stories that humanize God are archaic and lame. Cosmicist pantheism (together with existential, humanistic heroism) is better.
