The assumption right now is that every theropod had feathers of some kind somewhere. Some of them may have lost them as adults, or only be partially covered, the skin impression information is somewhat inconsistent. But generally yes, theropods looked very much like big carnivorous flightless birds, plumage and all. Velociraptor for instance likely had what today we would describe as wings.
- krylon 9y agoJurassic Park lied to me! Even though the link between dinosaurs and birds is mentioned explicitly. :( Would be interesting to see a remake that used all of the current knowledge about dinosaurs, what they looked and behaved like.
- bringtheaction 9y agoThe 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.
- krylon 9y agoNow 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.

- kkylin 9y agoI 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...
- saget 9y agoWhales 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
- pvaldes 9y agoMany african big predators chase at night and sleep all day.
- khedoros1 9y agoLife-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.
- krylon 9y ago> 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. :.-(
