28. Neanis
Discovered in 1913, the Neanis is a bird species that not much is known about. Paleontologists believe that it is an ancestor of the toucan and the woodpecker. It’s estimated it lived from the Late Wasatchian period to the Early Eocene era.
The Neanis was found in the Green River Formation located in areas of Colorado, Utah, and Wyoming. Just one complete but not well-preserved skeleton was found in the early 20th century. Experts estimate that the Neanis was related to the woodpecker and toucan because of the shape of its foot and the placement of its toes. The Neanis has the ability to turn its outer toe backward.
