Raptorex was a tiny cousin of T. rex that lived about 70 million years ago. It had a big head, long legs for running, and tiny arms with just two fingers. Even though it was small, it already looked like a mini version of the giant tyrannosaurs!1

Ebyewuunyisa

1

Raptorex is known from just one skeleton, which is a very young juvenile about three years old.1

2

Its tiny arms and big head are features that scientists once thought only appeared in giant tyrannosaurs, but Raptorex shows they evolved in small dinosaurs first.2

3

Many scientists now think Raptorex might actually be a baby Tarbosaurus, a close relative of T. rex from Mongolia.1

4

The only Raptorex fossil was bought at a gem and mineral show in Arizona before a scientist studied it.1

5

A fish bone found with the Raptorex skeleton helped scientists figure out that it probably came from the Late Cretaceous Nemegt Formation in Mongolia.1

6

Raptorex was about the size of a large dog, only 2.5 to 3 metres long and weighing around 65 kilograms.1

Ebibuuzo ebisinga okubuuzibwa ku Raptorex

?How big was Raptorex?

About 2.5 to 3 metres (8.2 to 9.8 feet) long and weighed around 65 kilograms (143 pounds), about the size of a large human.1

?Was Raptorex a dinosaur?

Yes, Raptorex was a small tyrannosaurid dinosaur, a close cousin of T. rex.1

?Did Raptorex have feathers?

The sources don't say for sure, but many small tyrannosaurs had feathers. Since Raptorex was a juvenile, it might have had a light covering of feathers, but no direct evidence is known.1

?What did Raptorex eat?

Raptorex was a meat-eater, like other tyrannosaurs. It probably hunted small animals or scavenged, using its big head and sharp teeth.1

?Is Raptorex a baby Tarbosaurus?

Many scientists now think Raptorex might be a juvenile Tarbosaurus, a close relative of T. rex from Mongolia, because the only skeleton looks just like a baby Tarbosaurus.13

?When did Raptorex live?

It probably lived about 70 million years ago, during the Late Cretaceous period, in what is now Mongolia.1

Omumenyi w'enfumo

Enfumo: Some people think Raptorex is a separate species that lived in the Early Cretaceous, about 125 million years ago.

Amazima: Scientists now agree that Raptorex is a juvenile tyrannosaur from the Late Cretaceous, about 70 million years ago, and it may be the same as Tarbosaurus.1

The only Raptorex fossil was bought by Dr. Henry Kriegstein at a fossil show in Tucson, Arizona. He showed it to paleontologist Paul Sereno, who named it Raptorex kriegsteini in 2009.1

Scientists still argue whether Raptorex is a valid genus or just a baby Tarbosaurus. More fossils are needed to settle the debate.1
