I think the only real reasons Tigrex is even in Ruins Field is because there is wide open Fields for it to travel and hunt,from the area possibly being bigger than it is right now,from the area possibly being close to the desert or Capcom just throwing darts at a wall at random monsters to put them in Ruins Field.
