Qianlong

名字的意思： “dragon from Guizhou”1

吃：植物長脖子恐龍侏羅紀早期

Qianlong was an early long-necked dinosaur that lived in what is now China. It is special because scientists found its eggs and babies next to the grown-ups, which helps us learn how these dinosaurs raised their families.1

酷東西

趣味知識

Qianlong had leathery eggs, like some modern reptiles, not hard shells like many dinosaurs.1

The eggs were about 11.5 cm by 9.4 cm (4.5 by 3.7 inches), which is big for an early sauropodomorph.1

Scientists found five clutches of eggs in a small area, suggesting Qianlong nested in colonies.1

The babies inside the eggs were in a posture that is halfway between how crocodiles and birds sit before hatching.1

All the embryos were at the same stage of development, meaning the babies hatched at the same time.1

Qianlong lived about 199 to 193 million years ago, during the Early Jurassic period.2

發現: Qianlong was named in 2023 by a team of scientists including F. Han. The fossils were found in Guizhou Province, China, and include three adult skeletons and five clutches of eggs with embryos.1 2
仍有爭議: Scientists are still debating whether all early sauropodomorphs had leathery eggs, or if that was special to Qianlong.1
