Whales have a lot of fat (and I'm assuming other insulating tools) to keep them warm in cold water, their bodies aren't designed to be beached in warm air under the sun. Elephants, while not as large as a trex, can survive the hot African savanna no problem so I feel evolution could handle making a trex live in moderate temperatures without to much of a problem

The question, though, is with or without feathers. Elephants have huge head radiators and no plumage, so there is a point to the article

True, good point!
