  • The Today world news and the today top world news
    brings you a news of an ancient bird, A
    120-million-year-old bird sported not one, but
    two tails, paleontologists found. The discovery
    indicates to a complicated evolutionary path in
    the tails of birds we see today, National
    Geographic reported.

  • The second-oldest known bird, Jeholornis, lived
    in what is today China along with other feathered
    prehistoric animals. Fossils show the Jeholornis
    was the size of a turkey, had claws on its winged
    forelimbs with three small teeth in its lower
    jaw.
  • Now, paleontologists are looking at the rear end
    of the huge birds. They not only possess a
    long-fan feathered tail but also a second tail
    frond.

  • "The 'two-tail' plumage of Jeholornis is
    exceptional," according to a study published in
    the Proceedings of the National Academy of
    Sciences. The study was led by Jingmai OConnor
    of the Chinese Academy of Sciences in Beijing.
  • Much like today's male peacocks which sport
    colorful feathers to attract their mates, the
    study suggests only male Jeholornis had the
    eye-catching tail fronds.

  • "Clearly the display aspect of the frond would
    have been indisputable," says paleontologist Mark
    Norell, of the American Museum of Natural History
    in New York, who was not part of the study. "It
    calls to mind living birds, even peacocks, which
    display broad plumes of feathers."
