they are extinct- in common thought, but they may be out there, just leave em alone in my word lol
yes there indeed have. a close friend of mines father is geologist and has spent plenty of time hiking around the new guniea highlands. he has some interesting storis of local who claimed that they have seen a thylacine-like animal. his son has seen UFO's and claimed for years he saw a flamingo at lakes entrance (and i STILL failed to convince him otherwise zoopro!!!)
