The most recent Jurassic Park movie has a solution to this problem. In it they say that they had to use genes from amphibians together with the dinosaur genes in order to create their animals. This way the issue is reconciled.

Now that I think of it, they mentioned the amphibian DNA in the first one (and the book), too, to explain why the dinosaurs were suddenly able to procreate. Still, a life-size velociraptor ot T-Rex covered in a coat of feathers must be quite a sight.

  I wonder how much the CGI production costs would rise :-)

  I think someone may have posted this already, but in case not: https://www.smithsonianmag.com/smart-news/t-rex-skin-was-not-covered-feathers-study-says-180963603/ https://www.smithsonianmag.com/smart-news/t-rex-skin-was-not... "T. Rex Was Likely Covered in Scales, Not Feathers" What I don't understand is how something the size of T rex doesn't just die from heat shock whenever it breaks into a sprint. I vaguely recall reading somewhere that one of the dangers facing beached whales is that they start to overheat rapidly. Did big dinosaurs just live in cooler environments? Do they have better ways to dissipate heat? Did they like dipping in lakes and ponds? I'm sure someone would have asked these questions already, but no idea what current thinking in the field is...

    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

      True, good point!

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

    Many african big predators chase at night and sleep all day.

  Life-size velociraptors were apparently about turkey-sized. There were others in the same family that were larger, and a bit more similar to the animals depicted in the book/movie.

    > Life-size velociraptors were apparently about turkey-sized Jurassic Park lied to me twice Next thing, somebody will point out that there are no 12-year-old girls that routinely use SGI workstations. :.-(
