Product Description
After the dinosaurs became extinct 65 million years ago, the mammals grew to adjust to the wide range of habitats left vacant by the extinct reptiles. Once shrew-like in appearance and lifestyle, the mammals quickly expanded into different life forms and environments to become the dominant group of land-dwelling vertebrates as well as a major part of aquatic life. There are about 4,000 species of mammals. These beautiful playing cards, illustrated by the artist Cecilia Fitzsimmons, bring to life the vibrant diversity of 54 familiar animals of the North American continent.
