Montana is the US state where spectacular prehistoric finds are regularly made. That's exactly where Henry lives and witnesses how researchers excavate a Tyrannosaurus Rex on his parents' ranch that is almost completely preserved. What a sensation this is! No wonder Henry only dreams of dinos at night. As Magic Man, he can tame them with his magic wand and even rescue a baby dinosaur from the clutches of a Quetzalcoatlus! And he witnesses how an enormous mudslide finishes off the primordial animals ... On the occasion of the excavation of a T-Rex skeleton for the Dutch Museum of Natural History in Leiden, Thé Tjong-Khing came up with this story, in which he oscillates between fiction and fantasy. Little dino experts will be thrilled!.
