吃：植物長脖子恐龍侏羅紀早期到侏羅紀中期

Ceratocaudia was a small, plant-eating sauropod dinosaur that lived in what is now India during the Jurassic Period. It had a horn-like crest on its tail bones, and scientists think it might have used its tail to scare away predators.1

酷東西

趣味知識

Ceratocaudia is one of the smallest known macronarian sauropods, measuring only about 7 metres (23 feet) long.1

The horn-like crest on its tail vertebrae gave the dinosaur its name, meaning 'horned tail'.1

Scientists think Ceratocaudia might have been a dwarf species because the only known skeleton is from an old individual but is still very small.1 3

The holotype skeleton includes neck bones, tail bones, an ulna, thighbones, shinbones, and even finger and toe bones.1

Ceratocaudia lived in an estuary environment alongside petrified wood, clams, and a much larger sauropod that was about 20 metres long.1

A muscle reconstruction of the tail suggests Ceratocaudia could swing it as a mild deterrent against predators.1 3
