Paleontology team from the Chinese Academy of Sciences, Beijing, China, revealed that 120 million years ago, birds have two tails. These findings make the complex evolutionary paths of species of birds.
Launch Fox News, October 16, 2013, it was known from ancient bird fossils Jeholornis. Habitat in China with other pre-historic animals.
From fossil findings, Jeholornis a bird larger than a turkey, has claws on his wings, and there are three small teeth on the lower jaw.

Interestingly, the paleontologists also found Jeholornis males have long tails and of two. Not yet known what the function of the two heads, what is the support aircraft or only serves to lure the opponent type.
"Two heads are found in birds Jeholornis very baffling. This is a new evolutionary path to animal species of birds," said O'Connor Jingmai, research leader of the Chinese Academy of Sciences.
O'Connor added, a team of researchers to predict the function of one of the pieces just to attract the opposite type. Given the size of the long tail and a longer tail rather short, like the tail of the peacock.
"The function of one of the tail feathers filled colorful like a feature that is similar to the peacock, which is to attract attention of the opposite kind," said O'Connor.
However, according to Julia Clarke, a paleontologist from the University of Texas, the U.S., the functions of the two pieces is to create stability airport.
The majority concluded, one of the pieces that do not seem to have a specific function and evolve into a tail only in modern birds.
"The shape of the two pieces is a line of evolution in birds. However, the findings of two small birds Jeholornis is strange and odd," Clarke closed.
The results are published in the Proceedings of the National Academy of Sciences titled "Unique caudal plumage of Jeholornis and complex tail in early bird evolution."vivanews
