Fun Gallimimus Facts For Kids

The Gallimimus lived in Mongolia's Gobi Desert during the late Cretaceous period around 70 million years ago. The Gallimimus is a very interesting dinosaur and there is a theory behind how it got its name.

Several fossils or the Gallimimus skeleton were recovered from the Gobi Desert. Several areas of Asia also seemed to be the home for these dinosaurs.

Unlike other species of dinosaurs, members of this genus are well known and well written in history given the fact that many fossils of this theropod have been recovered to date. This group of theropods was very large and often seemed like easy prey for predators.

They had bird-like features and researchers often described them as ostrich-like. They were also called chicken mimics and were toothless.

Without strong teeth and arms it would have been very difficult for a Gallimimus dinosaur to save itself. Nonetheless, it had excellent jaw muscles and could scoop down anything from hard rocks to mud. The arm of a Gallimimus dinosaur is extremely important, as this helped it gather food.

Despite tits fragile body structure, it survived the Triassic, Jurassic, and Cretaceous periods. From Jurassic Park creatures to the creatures of today's time, to learn more about such wonderful animals check out our articles on the beaglier and the Australian mist.

Gallimimus Interesting Facts

How do you pronounce 'Gallimimus'?

This long tail early creature belongs to the group of some dinosaurs which are known as ostrich copycats or ornithomimids. Their comparison with modern ostriches is because they are similar in several aspects. The right pronunciation for the dinosaur Gallimimus is "GAL-i-MY-mes".

What type of dinosaur was a Gallimimus?

Based on studies done on the Gallimimus skull they are very similar in comparison to the earlier preserved ornithomimid. When we explore further it can be revealed that this species possessed legs, feathers, and large eyes, very similar to current day birds.

The Gallimimus liked living in a herd and the Gallimimus may have gulped down eggs of other dinosaurs. This bird-like theropod is the largest known ornithomimid; the same is mentioned in various books of different languages.

In which geological period did the Gallimimus roam the Earth?

The exact range of their time period on Earth can be estimated to be from the Triassic period to the late Cretaceous period, covering the Jurassic period as well. They are assumed to have roamed the world some 70 million years ago and had an omnivorous diet.

Their long beak and light weight gave them great speeds when it came to search for food.

When did the Gallimimus become extinct?

There can be plenty of reasons why the Gallimimus dinosaur became extinct. The major reason for their extinction is unfavorable climates of the Earth, which was a result of the asteroid collision.

Their body structure was relatively weaker as well when compared with other dinosaurs. The bone of their braincase was hollow and they mostly ate less nutritious food. Their search for food on the ground didn't help them much, hence it's believed that this bird-like dinosaur also swallowed rocks and dirt.

Where did a Gallimimus live?

During the late Cretaceous and the Jurassic period, the Gallimimus lived in the hot climate of the Gobi Desert of Mongolia. This long-neck ostrich-like dinosaur also lived in several other parts of Asia, although fossils of the specimen were generally recovered from Mongolia's Gobi Desert.

What was a Gallimimus's habitat?

A suitable Gallimimus habitat would be a hot, dry place, a desert to be more precise. Their long feet gave them a good grip when walking across stones and sand, whereas the head worked for mapping direction.

Who did a Gallimimus live with?

Members of this genus lived with many theropods on the ground. A Gallimimus either moved alone or moved in a herd so in most cases they lived amongst their own genus. The Gallimimus may have lived with other bird-like species. Modern-day birds like the ostrich and peacocks are the closest relatives of birds from the Jurassic period.

How long did a Gallimimus live?

The exact life span of this dinosaur is not known. It can be estimated that this chicken mimic species lived for 10-20 years unless hunted by other predators.

How did they reproduce?

Early reptiles reproduced in a very similar manner to reptiles of today's age. Young were fed on insects and guarded by their parents. The Gallimimus used to lay two to three eggs each breeding season and protected them from other large dinosaurs. A Gallimimus egg was often similar in length to the current-day ostrich egg length.

Their diet was carnivorous, whereas the Gallimimus ate both plants and animals. It's a tough competition between the Gallimimus and the Velociraptor when it comes to speed. Nonetheless, the velociraptor is the fastest.
