A paleontologist opinion may count?
Is not a good ideia. Do you now why palleontologists love the two novels? Is because Crichton made few descrptions of the dinosaurs as possible. Who decide what the dinosaurs look like in the novels is the reader and this make possible see these animals with a fair amount of acuracy that is superior of that of the films who are fixed in a comercial mark.
And try to make dinosaurs "acurate" will only make they look like this for a decade or less. New descoveries are made every day and our depction of what a dinosaur look as not near close to the concrete image that pepole like the Saurian devs want us to belive. Of course when come to dinosaurs like Dromeosaurs and Ornithomimosaurs we have already a good notion of what they look like in real life. But they are exception.
And they don't have to be treat with homegeinity. Its not because one single one raptor have X style of distribution of feathers that ALL others will be exacly the same nor they will be exact copies of todays creatures. The things that will be determine what a animal will look like is almost never considered by the paleoartists. This is because is almost impossible do this given to the fragmentary apacts of the ecosystems and the animals itself (and it is why we have so many raptors that look exactly like a bird of prey).
Two good exemples of this is the Edmontosaurus and the Ornitholestes. About of the Edmonto we think we know exactly what it looked for almost a decade and last year they found that theses animals had a g crest. And we have the Ornitholestes who always had a horn/crest but had recently change by a discover that we are just looking to a bronken bone.
So I don't like the ideia of a "acurate" vision because such thing dosen't exist in the first place. Unless we have a time machine, we never know how the vast majorite of the dinos really look like, we can only conceptualize based on solid evidence to try get closer to a acurate depcition, but will never will be acurate.
Have this in consideration one thing that the frontier team could make is try is fix major anatomical errors (like the manus and pes of almost every dinosaur) and launch a DLC with a improved version of the base Skin system that allow us to breed dinosaurs with other types of intergument (feathers and protofeather for coelurosaurs, spike-like quills for ornitopods, quills for non coelurosaur tetanuerans, spikes and osteoderms for sauropods, etc). With this two things we have the most acurate dinosaurs possible with don't lose the Jurassic Park style.
And about minor anatomical concerns like the size o dino X and the number of teeth of dino Y? Well, frontier have to diferent tinghs that allow such "errors" to not be errors de facto. First, this animals are artificials, just like a dog, so a Velociraptor of the size of a small Utharaptor is just like a Pitbull in comparasion with a chiwawa. But they don't even need to resouce in this, that is because they don't show the real specie name of any dinosaur. Maybe some of you don't noticed this, but all dinos so far have only they genus divulged and not the specie. And, again, a Cannis lupus and a Cannis familiaris are in the same genera, but a chiwawa is a lot diferent from a wolf. So small details like size or number of teeth are forgiven (thus details that pull of the animal of the entire family like the narines of the apato and the teeth size of the Majungasaurus need to be fixed in order to these excuse have sense).
Again, this can't be named as "acurate" depiction of theses creatures because such thing don't exist. But will drive us close to what the fossil record tell us and even manage to keep the the Jurassic Park style and trademarks. Something like the best of both worlds.
Last, I need to apologize for any gramatical or sentence error that I made. I'm not used to write in english very often, so if you se some error (and don't gramatical ones, feel free to discord to disagree with me) please feel free to correct me. c:
P.s. Sorry again. This time for make this wall of text to explain something that actually we all know, but I really want to explain the whole "science never are 100% sure" thing. if someone here dosen't know already.
