Who discovered the Raptorex?
Raptorex is a new species of meat-eating dinosaur, discovered in northwest China by Paul Sereno from the University of Chicago. The specimen is a young adult, but it wouldn’t have grown to more than 3 metres in length. It stood about as tall as a human, and wouldn’t have weighed much more.
Is Raptorex a real dinosaur?
Raptorex is a dubious genus of tyrannosaurid dinosaur. Its fossil remains consist of a single juvenile specimen probably uncovered in Mongolia, or possibly northeastern China. The genus name is derived from Latin raptor, “robber”, and rex, “king”.
Is Raptorex a juvenile Tarbosaurus?
LH PV18 may be the skeleton of a juvenile animal, which opens the possibility that the dinosaur called “Raptorex” is actually an immature growth stage of Tarbosaurus. It may turn out that Raptorex is the juvenile form of a large tyrannosaur species from which the adult is not yet known.
Where did Raptorex live?
A dinosaur with all the traits of a T. rex — big head, little arms, muscular legs — but only three metres long has been found in northeastern China. The paleontologists who identified the dinosaur, which lived tens of millions of years before Tyrannosaurus rex, have dubbed it Raptorex.
Is raptorex a member of Tyrannosauridae?
An additional tyrannosaurid, Raptorex, was initially described as a more primitive tyrannosauroid, but likely represents a juvenile tyrannosaurine similar to Tarbosaurus. However, as it is known only from a juvenile specimen, it is also currently considered a nomen dubium.
What is a Raptorsaurus?
1 : a carnivorous medium- to large-sized bird (such as a hawk, eagle, owl, or vulture) that has a hooked beak and large sharp talons and that feeds wholly or chiefly on meat taken by hunting or on carrion : bird of prey.
Did Raptors Really Exist?
Velociraptors were actually feathered animals. In fact, the raptors that terrorized Jurassic Park were based on a Velociraptor relative: Deinonychus antirrhopus, a much larger dinosaur that inhabited North America in the early Cretaceous period, about 145 to 100 million years ago.
How tall is a Raptorex?
An adult Raptorex was about 9 feet tall and weighed about 150 pounds, scientists say. The predator, nicknamed Raptorex, lived about 60 million years before the T. rex and was slightly larger than the human male, scientists said.
What was the largest Tyrannosaurid?
A fossil site in Canada has yielded the heaviest Tyrannosaurus rex specimen ever found—an animal that weighed an estimated 19,500 pounds in life, far heftier than most elephants alive today.
Is a raptor a dinosaur or a bird?
The Definition of a Raptor Technically, paleontologists define raptors, or dromaeosaurs, as theropod dinosaurs that share certain obscure anatomical characteristics.
Where did the name Raptorex dinosaur come from?
Raptorex is a dubious genus of tyrannosaurid dinosaur. Its fossil remains consist of a single juvenile specimen probably uncovered in Mongolia, or possibly northeastern China. The type species is R. kriegsteini, described in 2009 by Sereno and colleagues. The genus name is derived from Latin raptor, “robber”, and rex, “king”.
How old was the Raptorex when it died?
(Based on an analysis of its bones, the sole specimen of Raptorex appears to have been a full-grown adult six years of age). Analogizing from other early tyrannosaurs–like the Asian Dilong–Raptorex may have been covered with feathers, though as yet there’s no definitive proof for this.

How big was Raptorex compared to Tyrannosaurus rex?
Discovered in inner Mongolia by the famous paleontologist Paul Sereno, Raptorex lived about 60 million years before its more famous descendant Tyrannosaurus Rex –but this dinosaur already had the basic tyrannosaur body plan (big head, powerful legs, stunted arms), albeit in a diminutive package of only 150 pounds or so.
