Ocean Renegades! (Earth Before Us #2): Journey through the Paleozoic Era

When Ronnies parents go on a business trip and leave her with Miss Lernin for the week, Ronnie is sure shes in for a big, dinosaur-size adventure. After all, her last trip with Miss Lernin involved real-life dinosaurs! So, when they end up at the aquarium's jellyfish exhibit, Ronnie is confused. Surely jellyfish arent as cool as dinosaurs, right? Wrong! Determined to show Ronnie just how interesting prehistoric life was before the age of the dinosaurs, Miss Lernin takes her back in time to the six parts of the Paleozoic era to study the earliest lifeforms on Earth, and how many left the ocean for life on land.
