👉 Pterodontia is a group of extinct reptiles that lived during the Early Cretaceous period, between about 68 and 53 million years ago. They were characterized by their large wingspan, long necks, and distinctive long tail feathers, which allowed them to soar and glide through the air like birds. Pterodontians are known for their remarkable ability to survive in harsh environments, including deserts, forests, and even caves.
