Some 148 million years ago, a bird no heavier than a robin died in what is now coastal China, and in dying, preserved the answer to one of paleontology's most enduring questions. The creature, named Zhengheornis buyu, carried a tail that was neither the long bony appendage of its dinosaur ancestors nor the fused pygostyle of modern birds — it was something in between, something many scientists had argued could not exist. Its discovery reminds us that evolution rarely leaps; it steps, and the steps are written in bone for those patient enough to find them.
