This is the tenth book in Joey’s adventures. Whilst reading his Dinosaur book, Joey discovers a page showing a book about Mega Fauna – animals that lived after the Dinosaurs. He wants to learn about Woolly Mammoths, and Sabre-Tooth Tigers. He wants to know if they were in his town, after the Dinosaurs. Do the Dinosaur Dig Team know about the Mega Fauna? But today there are jobs to do around the house. No time for a trip on the Tractor/Time Machine. And then there is the surprise that Joey’s mum and dad have for him that night.
