Kaatedocus

名字的意思： “small beam”1

吃：植物長脖子恐龍侏羅紀晚期

Kaatedocus was a long-necked sauropod that lived in what is now Wyoming during the Late Jurassic. It was smaller than many of its relatives, only about 14 metres long. Its well-preserved skull and neck helped scientists learn how sauropods held their heads.1 2

酷東西

趣味知識

Kaatedocus was named in 2012 by paleontologists Emanuel Tschopp and Octávio Mateus.1

Its name comes from the Crow Indian word 'kaate' meaning 'small' and 'docus' from Diplodocus, so 'small beam'.1

The only known specimen includes a nearly complete skull and a neck made of at least 14 vertebrae.1

The skull and neck together measured about 3.8 metres (12 feet) long.1

The fossils were originally thought to belong to Barosaurus or Diplodocus before being recognized as a new dinosaur.2

Scientists used CT scans and 3D printing to study Kaatedocus's neck vertebrae and learn how sauropods held their necks upright.1
