gauza bikainak

Datu dibertigarriak

1

Its neck bones had air spaces inside, like modern birds, which made its neck lighter.1

2

Scientists think it had feathers that looked like those of an ostrich.1

3

It lived alongside the giant dinosaur Gigantoraptor and the predator Alectrosaurus.1

4

No stress fractures were found in its foot bones, meaning it probably didn't run too hard or too often.1

5

Its third toe bone was not pinched at the top, so its foot was not built for extreme speed like some other ornithomimids.1

6

The first fossils were found by an expedition led by Roy Chapman Andrews in 1923.1

The first fossils were found in 1923 in Inner Mongolia by an American Museum of Natural History expedition. In 1933, Charles Gilmore named them Ornithomimus asiaticus. In 1972, Dale Russell gave them their own genus, Archaeornithomimus.1
Oraindik eztabaidagai
Scientists are not sure whether Archaeornithomimus was a true ornithomimid or a more primitive ornithomimosaur. Some studies place it inside the family, others outside.1
