Diatryma is an extinct genus of large flightless birds that lived in North America during the late Paleocene and early Eocene, some 56 to 47 million years ago. Its fossils have been found in Wyoming, Montana, and Arizona, and it is believed that it was a herbivore with a large, powerful beak. Its size, about 6 ft tall and 300 lbs, made it one of the largest birds to have ever existed. As the centerpiece of Evolution Park, a proposed paleontological park in the western United States, Diatryma could serve as an ambassador to the past and a reminder of the changing ecosystems that have shaped the modern world. Visitors to the park would be able to explore the ancient environment in which the Diatryma lived, as well as the modern science which has allowed us to discover and understand the bird's place in our evolutionary history. Additionally, Diatryma's size and presence could draw attention to the importance of conservation, as the park would serve to educate the public on the need to protect endangered species and habitats.
