Dimetrodon

Dimetrodon was a synapsid that lived in North America around the Early Permian between 295 and 272 million years ago and was discovered by the famous American paleontologist Edward Cope in 1878. It resides within deserts, tropical jungles, forests, and vast grasslands and is known to prey upon other animals both in the water and on land. Many species within the genus such as Dimetrodon grandis, Dimetrodon milieri, and Dimetrodon limbatus have been well-knowned and described, spanning from the size of a small cat to as large as 18 feet in total body length.
