Green River Formation fossil replica, Fossil Butte National Monument, 2016.
Summary
A broad range of species can be found in the Green River Formation's ancient fossil lake. This 5.5-inch long bat is the most primitive bad known to science. Claws on each finger of its wings indicate that it was probably an agile climber and crawled along and under tree branches while searching for insects.
