What about sightings and adventurers? I'm sure hundreds of bored people already tried to find the beast. Yet with no luck. Not even a bone was found. Or was it? The squid is still a different topic I think, as we knew that there were large squids before. There is no great difference between normal sized squids and the huge ones, except that those grow bigger. It can grow to 10 meters, but it could be also 2,3,4,5,x meters long. A Mountain-Wookie is a different thing as there are no ancestors , no relatives. Neanderthaler men did exist and mixed up with cro magnon people, most of them probably were slain (but there are proofs, that half neander half cro m. were actually born.) It is an interesting thought. But the problem is, that those people were wandering to the west (upon bones found), so the last of them lived somewhere in Western Europe. I don't see any chance to find one in the US.
