Gallimimus
Gallimimus bullatus (Gallimimus · Gallimimus)
Known only from fossils. The IUCN Red List assesses only species extant since 1500 CE, so fossil taxa are not assigned a category.
💡 Everyday Comparisons for Size, Mass & Speed
- 💡 An estimated body length of about 6 m (representative value for the genus) is about 1.3 times the length of a passenger car (about 4.5 m), and a weight of about 490 kg is about seven adult men (about 70 kg each) (Comparison).
- 💡 An estimated top speed of 47–55 km/h is similar to the speed limit on city roads (50 km/h) (Comparison).
Reference standards: coach bus ~12 m, mid-size car ~4.9 m, compact car ~1 t, basketball hoop 3.05 m, credit card 8.56 cm.

📖 1. Overview
Gallimimus bullatus (genus Gallimimus) was an ostrich-like theropod that lived in Mongolia during the Late Cretaceous, and its name means "chicken mimic" (because its neck vertebrae resemble those of a chicken). Among ostrich-like dinosaurs, it was on the large side, standing about twice as tall as a human.
🦴 2. Anatomy & Morphology
It walked on two legs and had a toothless beak. Because there is evidence of feathers in close relatives, it very likely had feathers as well.
🔍 3. Fossil Record & Paleoecology
It was omnivorous. With an estimated top speed of about 47–55 km/h, fast running was likely its main defense against predators. Because several individuals were found together in a single fossil bed, it may also have lived in groups.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
