Dromaeosaurs (Family Dromaeosauridae), any of a group of small to medium-sized carnivorous dinosaurs that flourished in Asia and North" />
Deinonychus was the model for the “Raptor” dinosaurs from the movie “Jurassic Park” (1993). The name Raptor now applies to
Deinonychus antirrhopus is one of the best-known dromaeosaurid species and also a close relative of the smaller Velociraptor found in younger late Cretaceous rock formations in central Asia. The clade they form is called Velociraptorinae.
“Velociraptor and Deinonychus are very similar,” says Brusatte. “The main difference is size: Velociraptor was the size of a small dog, while Deinonychus looked more like a pony. I think the Jurassic Park Velociraptor was also partially based on Utahraptor, which is even bigger – horse-sized.”
The “raptors” featured in Jurassic Park were actually modeled after the closely related dromaeosaurid Deinonychus. In both the novel and film, paleontologists unearth a skeleton in Montana, far from the Velociraptor range of Central Asia but characteristic of the Deinonychus range.
Crichton once apologetically told Ostrom that he decided to use the name Velociraptor instead of Deinonychus for his book because he felt the former name was “more dramatic. p>
Recently, scientists discovered Velociraptor’s oldest known relative: a three-foot-long, fluffy dinosaur called Hesperornithoides miessleri. This little hunter was covered in feathers and had a sickle-shaped claw on each foot. It lived in the late Jurassic period, around 164 to 145 million years ago.
Utahraptor is the largest of all raptor dinosaurs. It is also the oldest of this family, living around 125 million years ago. Utahraptor made famous by starring in Jurassic Park.
The huge, deadly raptors portrayed in the movies are dead wrong. In reality, Velociraptor was only a few meters tall and had feathers. It was basically a larger, predatory chicken.
Jurassic Park – which brought Velociraptor into the spotlight – included a disturbing scene in which the dinosaur tapped the ground with its claw to help it find prey – in this case, kids.
Their overall size and shape resemble those of a handful of dinosaur species, including the infamous Velociraptor; even their claws are claw-like.
After examining the skull, scientists named the species Dracorex hogwartsia, the “Dragon King of Hogwarts”, after the fictional Hogwarts school in JK Rowling’s Harry Potter books. Some scientists believe the skull actually belongs to a young Pachycephalosaurus.
In the 1993 film Jurassic Park and the novel it is based on, one of the dinosaurs depicted is the Dilophosaurus. The film shows him with a ruffle around his neck and shorter than actor Wayne Knight (1.70 m), who plays the role of Dennis Nedry, who is killed by the poisonous-spitting Dilophosaurus.
“Tyrannosaurus” is Greek for “tyrant lizard,” and “rex” means “king” in Latin. So Tyrannosaurus rex was “king of the tyrant lizards.”
