It’s more “ELI9-12”, but if you want to take an accessible and comprehensive deep dive into the evolutionary paths of prehistoric animals, I highly recommend “Dinosaur Empire!” by Abby Howard. It’s the first comic book in a series all about the concepts of the evolutionary tree, it’s amazingly detailed and very fun.
What made a reptile a dinosaur specifically was the special hips; their legs went straight down underneath them like a horse or dog or, ahem, ***bird***, not out to the side like an alligator or iguana or ***any*** modem reptile.
All those gigantic ancient reptiles that you’re told aren’t technically dinosaurs? I’ll bet they’ve got their legs sticking straight out the side like an alligator.
I may be way over simplifying it but the way I explain to high schoolers how all dinos are reptiles but all reptiles aren’t dinos is: dinos are terrestrial, have legs under their bodies not sprawled out from the sides, & laid hard shelled eggs in nests. These 3 characteristics exclude all the groups I used to think were dinosaurs when I was a kid!
