I can't comment on Dyslocosaurus, as I don't know much about it. But I
was including the North Horn along with "non-northwestern US" localities
- Alamosaurus seems not to have gotten as far north as the area
currently producing the Hell Creek or Scollard Formations, which is
where T. rex is primarily known from.
