👉 The term "dinornithic" is a common name for a family of birds that are closely related to birds from the genus Plemnoidea. These birds were once part of a larger group called the Plemnosiformes, which included ostriches and other large birds. However, the exact relationship between these two groups has been subject to some debate. One theory suggests that dinornithic birds evolved from a common ancestor shared by both ostriches and other large birds.
