Hamititan

名字的意思： “Hami giant, named after Hami city in China where it was found”1

吃：植物長脖子恐龍白堊紀早期

Hamititan was a huge, long-necked plant eater that stomped around China about 130 million years ago. It had a very long tail made of special bones. Scientists know it from just a few tail bones, but they think it was as long as a big bus!1 3

趣味知識

Hamititan is known from only seven tail bones and three chevrons, which are bones that help support the tail.1 3

Its tail bones were procoelous, meaning they were cup-shaped at the front and ball-shaped at the back, which made the tail flexible and strong.2

A small theropod tooth was found right next to Hamititan's tail bones, suggesting a meat-eating dinosaur may have nibbled on its carcass.1

Hamititan lived in the same place as the pterosaur Hamipterus, which flew in the skies above. But Hamititan was a dinosaur, not a pterosaur.1

The name Hamititan comes from Hami city and the word titan, which means a giant from Greek myths.1

Hamititan was a titanosaur, a group of sauropods known for their huge size and wide bodies.1

迷思破解王

迷思： Some people think Hamititan was a pterosaur because it was found in the Hami Pterosaur Fauna.

真相： Hamititan was a sauropod dinosaur, not a pterosaur. Pterosaurs are flying reptiles, not dinosaurs.1

化石紀錄: The Paleobiology Database 收錄 1 筆3
發現: Hamititan was found by the Hami field team of the Institute of Vertebrate Paleontology and Paleoanthropology in 2013, in the Hami region of Xinjiang, China. It was named by Wang and colleagues in 2021.1 3
仍有爭議: Scientists are not sure exactly how long Hamititan was, because they only have tail bones. The 17 metre estimate is based on comparing with other titanosaurs.1
