Description

Gigantoraptor was a large dinosaur belonging to the oviraptorosaur family that lived in Mongolia during the Late Cretaceous period.
Its name means “giant thief,” which is derived from its relation to Oviraptor, which was wrongly given the infamous reputation of being an egg thief.
It stood at a height of about 5 meters and is estimated to have weighed 1.5 tons, making it the largest oviraptorosaur dinosaur in history.

The Truth About Its Massive Size

The only Gigantoraptor fossils found so far are very fragmentary, such as a lower jaw and vertebrae.
However, it was later found that these fossils belonged to a juvenile, which suggests that even larger adult fossils may one day be discovered, a possibility that has attracted the attention of paleontologists.

Despite its gigantic size, Gigantoraptor had a lightweight skeletal structure.
Because of this, while its height was comparable to a Tyrannosaurus, it is presumed to have been much more agile.

It is presumed to have been agile in its movements.

Herbivore or Carnivore? The Diet Debate

Since Gigantoraptor was a theropod that had a toothless, hard beak, its diet is a major mystery.
Initially, its enormous size led researchers to conclude that it was a herbivore.
However, its large, well-developed forelimbs and sharp claws are not typical characteristics of herbivores, so the debate continues to this day.

Appearance and History of Discovery

Gigantoraptor has a unique discovery story, as its fossil was found by Xu Xing, a Chinese paleontologist who appeared on a Japanese television show.
This discovery has been a very important clue for understanding the evolution and diversity of the oviraptorosaur family.

It is also believed that Gigantoraptor was covered in feathers, but since no definitive evidence has been found, its appearance remains shrouded in mystery.
