A Prehistoric Ridge

I marched over to the bottom shelf of the bookcase, hunting for uncharted territory. Wedged between two thick green encyclopedias, a ribbed wooden honey dipper was sticking out like a spiky tail, and right below it lay a jagged pinecone scale and a green plastic toy stegosaurus. That was clearly my calling! I shoved the little plastic dino forward with both paws, then propped the pinecone scale right behind its backplates like extra armor. When I thumped my back foot down with a mighty roar, it didn't budge an inch. Our Jurassic stronghold is totally fortified!
