ደስ ዝብሉ ሓቅታት

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
