Bagaraatan was a small, fast meat-eating dinosaur that lived in what is now Mongolia. It had a strong jaw with sharp teeth and long, slender legs for chasing prey. Scientists think it was about as long as a car!2

Mfundo zosangalatsa

1

Bagaraatan had a tail that was not very flexible near the body, because many bones in the tail were locked together.2

2

The first fossil of Bagaraatan was found in 1970 by Zofia Kielan-Jaworowska during a Polish-Mongolian expedition.2

3

At first, scientists thought Bagaraatan was a mix of different dinosaur parts, but later studies showed it is likely a small relative of Tyrannosaurus.1

4

Bagaraatan was about 3 to 3.5 meters long, which is similar to a large Deinonychus.2

5

The shin and ankle bones of Bagaraatan were fused together, giving it a strong lower leg.2

6

Bagaraatan had two holes in the back part of its lower jaw, which is unusual among theropod dinosaurs.2

Mafunso ofunsidwa kwambiri okhudza Bagaraatan

?How big was Bagaraatan?

About 3 to 3.5 metres (10 to 11.5 feet) long, which is about as long as a small car. It stood less than 1 metre (3.3 feet) tall at the hips.12

?What did Bagaraatan eat?

It was a meat-eater. It had strong jaws with sharp teeth and long legs for chasing prey, so it was probably an active predator or scavenger.2

?Was Bagaraatan a dinosaur?

Yes, it was a theropod dinosaur from the Late Cretaceous period. It lived in what is now Mongolia.1

?Is Bagaraatan related to T. rex?

Yes, scientists now think Bagaraatan was a small relative of Tyrannosaurus rex. The fossil is from a juvenile tyrannosaurid, one of the smallest known.13

Wothetsa nthano zabodza

Nthano: Bagaraatan was a bird-like dinosaur with feathers.

Zoona: Scientists have not found any evidence of feathers for Bagaraatan, and it is now thought to be a small tyrannosaurid, which probably had scaly skin like other tyrannosaurs.1

Bagaraatan was named in 1996 by Halszka Osmólska based on a partial skeleton found in Mongolia. The skeleton was discovered by Zofia Kielan-Jaworowska in 1970.42

Scientists are still debating whether Bagaraatan is a true tyrannosaurid or a close relative, and whether the fossils include bones from more than one animal.1
