Sydney: Australian scientists have uncovered several new species of mammals in the remote forests of Papua New Guinea (PNG), media reported on Wednesday.

Team leader Euan Ritchie, an ecologist from Melbourne's Deakin University, said 40 cameras were installed in the Torricelli mountain range in the remote north-west of Papua New Guinea to capture the first images of endangered tree kangaroos but in the process they have also discovered three new species of previously unidentified mammals, according to Xinhua.
