Qianlong

Naam beteken: “dragon from Guizhou”1

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

Prettige feite

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

KI-prent van Qianlong — 'n KI-prent van hoe Qianlong dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Vir dino-kenners

Wetenskaplike naam: Qianlong
Benoem deur: Han et al. 20232
Groep: Langnekke
Familie / klade: Sauropodomorpha2
Klassifikasie: Sauropodomorpha2
Ouderdom van die rotse: 200 tot 193 miljoen jaar (Sinemurian)2
Rotsformasies: Ziliujing2
Lande: China2
Fossielrekords: 1 in The Paleobiology Database2
Ontdekking: 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
Steeds omstrede: Scientists are still debating whether all early sauropodomorphs had leathery eggs, or if that was special to Qianlong.1
