Sail-back vs. Shark-tooth

'His huge flattened tail means he'll catch up to you, and his meat-hook-like claws mean you will suffer.' The Sail-back is book one from the second pair of Dinosaur Fights gamebooks, where you will use a soul time-portal to transport your spirit back in time 95,805,293 years ago to inhabit and control the body of a real dinosaur and have it fight its greatest enemy in the prehistoric world. In this thrilling game, your soul will be sent into the body of the famous Spinosaurus, possibly the largest predator to ever walk the earth. You will use jaws, claws and strength to answer the ultimate question: can you defeat the second largest predator, Carcharodontosaurus?
