What if dinosaurs had not died out? What if whole colonies of the prehistoric beasts had survived on a remote island off the coast of South America? This adventure in the best-selling 'Ology series offers young dinosaur lovers a tantalizing taste of what that would be like. The year is 1907, and young adventurer Raleigh Rimes is on an expedition to South America with real-life explorer Percy Fawcett. There he discovers the unimaginable: living dinosaurs roaming the rain forest! Presented as a journal detailing their extraordinary (and hairraising) encounters with the amazing beasts -- fearsome Tyrannosaurus rex, pack-hunting allosauruses, predatory velociraptors, armored triceratops, and other species -- Dinosaurology is filled with flaps and booklets offering dinosaur lore, along with such novelties as a sample of dinosaur skin, a pouch of ground stegosaurus horn, and more.
