Fun Facts
- The name Deinocheirus comes from Greek and means “terrible hand, which is unusual“.
- It is likely to have had feathers, with the bone structure of its tail and arms suggesting so.
- It ate mainly plants, but seems to have consumed anything it happened to find, including fish and other smaller animals.
- For many years, only a pair of its huge arms were found, with it taking until 2006 before anyone found a more complete fossil.
- Studying the fossil remains showed their previous ideas were wrong, as Deinocheirus was an ornithomimosaur but very different from similar species.
