You know, in the JP/JW universe, that's exactly what pure Pteranodons look like. At least, just their JW trilogy looks as of now. The Prologue short film confirms this during the Cretaceous sequence. The other variants still don't have an in-universe explanation, however. Though I would suspect the same.
And get this: The whole dinosaur design "accuracies" and "inaccuracies" in the JP/JW film series universe is really not what those online are wanting to perceive it as.
I can only say, from the scientiffic piont of view, the Lost World Pteranodon is the most realistic one of all JP/JW movies. In The Prologue short film they showed the design of the JW Pteranodon, because its the design of the JW series , thats the only reason .
In this creataceous scene were some cool new aspects, like the protofethers on the back of the T-Rex , but many other things were waaayyyyy out of scientiffic accuracy .
1. ALL Pteranodon in the Prologue were either juveniles or femeles !.... Not only one MALE with a big headcrest was on screen.
The Quetzalcoatlus was either massive oversized or all the Pteranodon on the Dinsaurcorps were very young individuals.
Qutezalcoatlus should have 10-12m wingspan and Pteranodon 6-7m. If the Pteranodon feeding from the corps would have 6m wingspann in that scene , the Qutezalcoatlus would have at least 24m !..... I hope they make him not such a moviemonster like the 60m JWLK Mosasaurus. (JW Mosa was much better 18-25m which is still very big,but ok )
2. Giganotosaurus lived earlier in the cretacous of south amerika, while T-Rex live much later in North Amerika. The new Giganotosaurs design of the Prologue resembles much more an Acrocanthosaurus, if you just compere the outlines.
I really like JWE and JWE2 and all JP and JW movies, but a lot of creatures are made very realistic while others realy look more like hybrids , which is ok.
And get this: "paleo accurate 100% genome" Skins would look more like "scientific accurater modells " from this "real universe" !
If you don´t like such skins, it´s OK , but for JW universe we have right now the most Skins.
A lot of people would like an 6m Dilo like in the ORIGINAL NOVEL " Jurassic PARK" , and for all which want steven spielberg shrinked down dillo, there it is ingame.
Spielberg shrinked the Dilo to make it more diverse from the Raptors, thats all.
Ps. The JP Raptors are much more orientated in size and headshape to Deinonychus , because this lived in Montana ,... velociraptor was never found there !
Spielberg used the name Vellociraptor because of its translation, it fitte much better in the "Montana scene" for the comparisson of Dinos and Birds.
Funfact: Dakotaraptor, from the Hell-Creek-formantion looks allmost perfect like our ingame "Velociraptors". ( A bit larger and more protofethers may be....lol)
