Professor Barrister's Dinosaur Mysteries #2: the Case of the Armored Allosaurus

In this second installment of the series, world-famous paleontologist Professor Reginald Barrister and third-grade dinosaur experts Nate and Emily travel back to dinosaur times to investigate a mysterious Allosaurus fossil. The fossil shows the dominant predator of Jurassic North America with large armor plates across its back, but Allosaurus didn't have armor--or did it? Professor Barrister, Nate and Emily will have to brave gigantic sauropods, spike wielding herbivores, and of course the monstrous Allosaurus to solve the mystery!
