Dinosaur Empire!: Ronnie is just a normal fifth-grader trying to pass her science class’s impossible quiz on the history of dinosaurs . . . until she runs into her neighbor—Ms. Lernin, a retired paleontologist. Ronnie and Ms. Lernin travel back through time to experience the age of the dinosaurs firsthand. They visit three important time periods of the Mesozoic Era: the Triassic, the Jurassic, and the Cretaceous. Along the way, Ronnie finds herself face-to-face with real-life dinosaurs and reptiles, like Stegosauruses, Velociraptors, and Thalattosaurs. She learns the differences between herbivores, carnivores, and omnivores, as well as between dinosaurs, insects, and reptiles. This hilarious and fact-filled graphic novel brings the age of the dinosaurs to life and shows the important effects this era had on our world today.

Ocean Renegades!: When Ronnie’s parents go on a business trip and leave her with Miss Lernin for the week, Ronnie is sure she’s 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 aren’t 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.

Mammal Takeover!: After the dinosaurs died out, Earth was by no means empty. There were still some little resourceful critters around who, without big predators to hunt them down, survived and thrived. Who were these scrappy creatures? Early mammals, our ancestors! In the Cenozoic Era, mammals rose to dominance and spread over the globe, resulting in woolly mammoths, saber-toothed tigers, and eventually all of humankind. In this adventure, readers will meet the three kinds of mammals—monotremes, marsupials, and placental mammals—as well as the other amazing ancient beasts they shared the Earth with during the Cenozoic Era. Travel along on this fascinating journey through time, from 66 million years ago to present day.
