👉 Pterotrachids are a group of extinct birds that lived during the Miocene period, approximately 25 million years ago. These birds were characterized by their long, slender beaks and large trachea, which allowed them to fly. Some examples include the ostriches from Australia, which have been described as having short beards and a curved beak, while others like the platypus, with its long beaks and rounded heads, are more closely related to birds.
