👉 The term "edaphosauria" refers to a group of extinct birds that lived during the Eocene epoch, approximately 65 million years ago. These birds were characterized by their large beak-like jaws and long bills, which allowed them to capture prey from trees or other sources. The exact number of species within this group is not known with certainty, but it is believed that there were at least five genera (including the genus "Edaphosaurus") that lived during this time period
