Gallimimus Ballatus


Gallimimus Ballatus lived during the late Cretaceous Period, about 70 million years ago, in what is now Mongolia. This dinosaur got its genus name, which means “chicken mimic,” because it has a lot in common with modern chickens, turkeys, and pheasants.

Fun Facts

  • This dinosaur’s species name, Ballatus was given to it because the back of its skull reminded scientists of a bulla, a piece of jewelry worn by boys in ancient Rome.
  • Gallimimus was part of the ornithomimidae family. Like other members of this family, it had a small head, a long neck, and long arms. It could probably run very fast because it had long, powerful legs and a long tail for balance. It also had hollow bones that contained air sacs and a respiratory system that was more efficient than that of mammals. Scientists guess it could run for long distances without tiring.
  • Like baby birds and alligators, Gallimimus babies had large eyes and small beaks. Scientists think mother Gallimimuses might have cared for their babies.
  • This dinosaur had a toothless beak, which contained thin tubes. Scientists think these tubes might have allowed the animal to slurp up aquatic animals and plants, similar to how a duck eats.
  • Gallimimus probably ate plants and small animals, such as insects.
