If you visited Wyoming around 50 million years ago, you might see a peculiar little bird racing through the hot, dense forests of the Eocene. About the size of a chicken, the creature would look something like a modern-day tinamou. In fact, that connection is pretty close to the mark. In a recent paper by Jackson School of Geosciences paleontologists, the prehistoric bird is revealed to be related to the flightless family that now holds ostriches, emus, and their kin.
