In this undated photo released by Conservation International, a golden-mantled tree kangaroo (Dendrolagus pulcherrimus) is seen after being discovered on Rapid Assessment Program (RAP) expedition to the Foya Mountains in Indonesia's easternmost Papua province in December 2005. Scientists discovered a 'Lost World' in an isolated Indonesian jungle, identifying dozens of new species of frogs, butterflies and plants _ as well as large mammals hunted to near extinction elsewhere, members of the expedition said Tuesday, Feb. 7 2006. This was first record of the species in Indonesia and the second known site on earth where it is known to exist. (AP Photo/Conservation International, Bruce Beehler, HO)
