Gallimimus Dinosaur Arm with Base Dimensions: 4" x 38" x 4" Scientific name: Gallimimus bullatus Age: Late Cretaceous Location: Mongolia Formation: Nemegt Gallimimus was a fast-running dinosaur with a very long, thin, flattened, toothless, horny beak, a small head, and a relatively large brain. The bottom front part of its beak was shaped like a shovel. It had large eyes positioned on opposite sites of its head, ruling out binocular vision (depth perception). It had a long neck, long tail, and long legs. Gallimimus was about 13-20 ft (4-6 m) long, was 6.3 ft (1.9 m) tall at the hips, and may have weighed about 970 pounds (440 kg). This is a Dinosaur Replica or Dinosaur Reproduction. One of our earth science resources and natural history museum supplies.
