Bats are found throughout America, but in certain areas of the country (e.g., the southwest) bats are the reason tourists visit. They gather and watch these mammals surge into the evening sky. The bats soar from cave systems by the thousands on their nightly foray. You have probably seen bats as they fed on the wing but mistook them for birds.
 

Scholarly illustrations, museum mock-ups, and even children’s cartoons show tyrannosaurs covered in feathers. Two new fossil descriptions give reasons to doubt the tales of feathered dinosaurs.
