An eleven foot long Dimetrodon grandis traverses an Earth that became cooler and dryer during the Early Permian period. 280 million years ago--long before the reign of dinosaurs--Dimetrodon emerged as the dominant land predator, a position they held for the next 20 million years. Contrary to their reptilian stance and dinosaur-like appearance, Dimetrodon are in fact more closely related to mammals, and hence to humans, than to dinosaurs or reptiles.
