A golden-fronted bowerbird, in the first photographic record of the species, is one of dozens of animals found in an Indonesian jungle dubbed "Lost World."

    An 11-member team of U.S., Indonesian and Australian scientists discovered the animals, including this new species of smoky honeyeater bird.

    The team took the first known photographs of Berlepsch's six-wired bird of paradise, which was described by hunters in New Guinea in the 19th century.

    The golden-mantled tree kangaroo -- thought to have been hunted to near extinction -- also lives there.

    The animals live in the Foja Mountains, an area in eastern Indonesia's Papua province with more than two million acres of old growth tropical forest.

    The scientists said they discovered 20 frog species, including a tiny frog less than a half-inch long, as well as four butterfly species and at least five palm plants.

    Some animals were remarkably unafraid of the team. Two long-beaked echidnas like this one let scientists pick them up and bring them to camp for study.

    Before the animals can officially be classified as new species, scientists will have to publish findings for review. The process could take six months to several years.

    "We've only scratched the surface," trip co-leader Bruce Beehler, of Conservation International, said.
