Why T-Rex looks hairy in ‘Jurassic World Dominion’!
There’s a hairy Tyrannosaurus rex in Jurassic World: Dominion’s prologue, which is notably different from how the dinosaur looked in past ‘Jurassic Park’ films.
In fact, there are multiple dinosaurs in the ‘Jurassic World: Dominion’ prologue that appear to be hairy, but most of them are new to the franchise whereas the T-Rex is a staple of the series. And the answer to why the T-rex and other dinosaurs are hairy in the upcoming film can be found in one of Jurassic Park’s earliest values: scientific accuracy.
Jurassic World: Dominion’s prologue contains footage that won’t appear in the actual film and is rather mean to offer a preview of what to expect. In the prologue, dinosaurs of all kinds go about their daily lives in the Cretaceous period; tri-horned Triceratops bathe in a river, long-necked Quetza lcoatlus fly around and fish, and a sneaky Oviraptor dines on a nest of abandoned eggs.
Tension rises when a Tyrannosaurus rex picks a fight with an even stronger predator, a Giganotosaurus. Flashing forward 65 million years, another Tyrannosaurus is pursued by a helicopter from the US Fish and Wildlife Service through a drive-in movie theater, to the terror of the moviegoers. Curiously, while the T-rex in the modern-day (the one originally seen in the first Jurassic Park movie) is still scaly, the T-rex in Jurassic World: Dominion’s prologue has thin hair covering its body.
It’s likely that this isn’t hair at all, but feathers; scientific evidence has shown that dinosaurs likely had feathers, just like their closest genetic relatives, birds. Since dinosaurs and birds derived from the same ancestral species, it’s almost certain that all dinosaurs would have had some amount of feathers, even if only vestigial ones. As feathers are unable to be fossilized like bone, little proof for dinosaurs’ feathers was found until somewhat recently, explaining why the original Jurassic Park’s T-rex didn’t have feathers.
