Mosasaurus: Mighty Ruler of the Sea Book

My kid absolutely loves this book, hence the 5 stars. The story is linear, interesting, and informative, but it has several grammatical errors, which drives me a bit crazy. I think spelling and grammar are important, particularly in children's books. It's nicely illustrated and my son loves the poster that was included; it's been hanging up in his bedroom for a couple years. If I were to rate it, I'd probably give it 3 stars because of the aforementioned grammar issues.
