I have recently started homeschooling my three 5 year olds. We will soon be covering a week's worth of dinosaurs. The curriculum (My Father's World) comes from the Young Earth perspective, therefore suggesting Answers in Genesis books, such as What Really Happened to the Dinosaurs?. Can you suggest any Old Earth books for 5-7 year olds that take on the topic of dinosaurs?Sadly, there is really only about one option. Unfortunately, it's out of print. But if you can find it, it's about the only game in town.

Our family has also enjoyed the Kingfisher Illustrated Dinosaur Encyclopedia. Even though it's written from a secular perspective and contains a few references to evolution, the science is correct. Personally, I've found that I prefer to use books with a few references to evolution than young-earth books. I feel like it's much easier to tell a kid to simply substitute "design" for evolution than trying to untangle young-earth errors. But maybe that's just me.
