Saturnalia

名字的意思： “named after the Roman festival of Saturnalia, because the fossils were found during Carnival”1

Saturnalia was one of the very first dinosaurs to ever walk the Earth. It was a small, speedy plant-eater that lived in what is now Brazil about 233 million years ago. Scientists have found several skeletons, making it one of the best-known early dinosaurs.1

酷東西

趣味知識

Saturnalia was only about 1.5 metres (4.9 feet) long, about the size of a large dog.1

Its skull was only about 10 centimetres (3.9 inches) long, giving it a tiny head compared to its body.1

Saturnalia had a long neck made of nine or ten vertebrae, which was about half the length of its trunk.1

It lived at the same time as the meat-eating dinosaur Staurikosaurus, which may have hunted it.1

Saturnalia is one of the oldest dinosaurs ever found, dating back to about 233 million years ago.1

The fossils were collected during the Brazilian Carnival, which is why scientists named it after the Roman festival Saturnalia.1

迷思破解王

迷思： Saturnalia was a plant-eater like later sauropodomorphs.

真相： Scientists now think Saturnalia was probably an omnivore or carnivore, eating insects and small animals, based on its teeth and skull shape.1

給恐龍專家

命名者: Langer et al. 19992
類群: 長脖子恐龍
科 / 演化支: Saturnaliidae2
分類: Sauropodomorpha2
岩石的年代: 237 到 227 百萬年 (Carnian)2
岩層: Santa Maria, Pebbly Arkose2

發現: Saturnalia was named in 1999 by Max Cardoso Langer and his team, based on three skeletons found in the Santa Maria Formation of Brazil during the 1998 Carnival.1
仍有爭議: Scientists still debate whether Saturnalia was a true sauropodomorph or more closely related to theropods, because it has a mix of features from both groups.1
