sasquatch
Okay, wait. If there is one sasquatch, there will be many sasquatch. There will be, or will have been, enough sasquatch to sustain the species for at least some period of time. There is not just one singular sasquatch (or Loch Ness monster for that matter) that is hundreds of years old.
Unless they are Sith Sasquatch and there can always only be two.
