Dinosaurs physical accuracy

No. The theory of feathers on large dromaeosaurs and Tyrannosaurs is in no way, shape, or form proven. This is just people wanting to complain.

Next thing you know they'll be demanding to see feathers on a megalodon. Where does it end? Just because a few of the smaller species of raptor were proven to have had feathers does not mean every single species of dinosaur had feathers. I see absolutely no reason to tear up our text books without conclusive evidence showing that they did have feathers.

No, because it's Jurassic Park. These are modified dinosaurs, not full-on. I also don't believe the whole feather thing on T-Rex, that'll just make it look like a silly giant chicken.

I've seen enough of this...

The more we learn about dinosaurs, the more we discover their immense simularities to birds, both in skeletal form, skin texture, and skin makeup.
Every single dromeosaur impression found has sported feathers. Not a single one has been scaley throughout. This pushes the idea that dromeosaurs (which happen to be most like birds) were indeed covered in feathers. All the way up to Utahraptor.

As for Tyrannosaurus, this is more tricky to debate. As of yet, there have been no large impressions of skin texture specifically from a Tyrannosaurus. There have been small fragments here and there, but nothing compared to the detailed impressions found with raptors. However, Yutyrannus completely brings feathers to light with the Tyrannosaur family. As it is well known its body was covered head to toe in feathers (due to, again, large and detailed impressions that signify were skin meets feather and amount of feather), it is now widely speculated that Tyrannosaurus itself at least had patches of feather here and there.

Think of a modern day elephant. Believe it or not, those animals are quite hairy. However, due to a blazing climate and the sheer size/mass of the animal, they do not have thick coats; just little patches here and there. Now imagine that mentality for a Tyrannosaurus. Due to the blazing temperature of North American Cretaceous climate and it itself being a very large animal, Tyrannosaurus is likely to have only supported patches of feathers here and there; not being completely covered.

And the notion that feathered dinosaurs can never be scary is absolutely ridiculous. That's only a matter of design. Imagine a feathered dinosaur, maybe a Utahraptor. Now, instead of thinking of the feathers in such a uniform and orderly fashion, make it more realistic. These are protofeathers, after all. Rough up the edges, split some ends, damage some surfaces; general wear and tear. Now, add blood stains.

Heck of a lot scarier than the naked scaley counterpart.

We are approaching a time in which we do not ask the question "Which dinosaurs are proven to have feathers?", but "Which dinosaurs are proven to NOT have feathers?" I often wonder how radically different our dipiction of dinosaurs would be if scientists knew they were closer related to birds than scaely lizards when they were first uncovered.

I think scientists need to just leave the jp franchise alone and get with the program that its entertainment, not a documentary... If they want to bring a realistic representation of dinosaurs on either the big screen or tv screens... Then they better make a walking with dinosaurs quality if not better documentary... just my 2 cents...
