Gallimimus

Gallimimus was probably an omnivore, eating both plants and small animals. It had a toothless beak and may have used it to filter food from water or to eat tough plants.21

Yes, scientists are confident Gallimimus had feathers. There is no direct evidence on Gallimimus itself, but its close relative Ornithomimus had feathers, so it is highly likely.21

Gallimimus could run at speeds of 42 to 56 kilometers per hour (26 to 35 miles per hour). That is more than twice as fast as a fit human, but slower than a modern ostrich.21

Gallimimus lived during the Late Cretaceous period, about 70 million years ago.21

Gallimimus fossils were found in the Gobi Desert of Mongolia. They were discovered by Polish-Mongolian expeditions in the 1960s.1

Gallimimus was about 6 meters (20 feet) long, 1.9 meters (6 feet) tall at the hip, and weighed around 400 to 490 kilograms (880 to 1,080 pounds). It was the largest known ornithomimid.21

Yes, there is some evidence Gallimimus lived in groups. A single bone bed contained multiple skeletons, suggesting they died together.21

The name Gallimimus means 'chicken mimic' in Latin. It was named because the bones in its neck look like those of chickens and other galliform birds.21
