Gigantoraptor was the biggest raptor,

and was similar to Archeopteryx and Velociraptor.

It was discovered by Chinese paleontologist Xu Xing

on April in 2005, in Inner Mongolia.

Gigantoraptor looks like Oviraptor,

but Gigantoraptor mostly stays near its nest,

keeping a watchful eye over its eggs.

Gigantoraptor seems, safe in the deserts of Mongolia,

but around once a month, there are

sandstorms which bury them alive.

Like most birds, male Gigantoraptors are

more colorful than females,

in order to attract females.
