Cynodont and Lichen

Andy travels back in time 220 million years, to the time of cynodont - a dog-like furry creature with excellent eyesight and a powerful sense of smell. His mission is to find some lichen, a moss-like plant that cynodont used as bedding in its underground burrow. Along the way he meets coelophysis, one of the earliest dinosaurs and one of cynodont's deadliest enemies. But, will Andy suceed in time before the museum opens?
