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! Stephen Penner is a children’s book author and illustrator who lives near Seattle with his wife, young son and even younger daughter. He got the idea for Professor Barrister’s Dinosaur Mysteries from a game he made up with his dinosaur-loving son. When not writing and drawing, he enjoys painting, reading and traveling.
