Ceratocaudia

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.13

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.13
