Naam beteken: “Da'an lizard, after the Da'an district in Zigong, Sichuan, China”1

Het geëet: PlanteLangnekkeLaat Jura tot Vroeë Kryt

Daanosaurus was a long-necked plant-eater that lived in what is now China during the Late Jurassic. It is known only from a young dinosaur, so scientists are not sure how big it grew. It was probably similar to another sauropod called Bellusaurus.1

Prettige feite

Daanosaurus is known only from a single juvenile skeleton, so its adult size is unknown.1

Its neck bones had deep air pockets called pleurocoels, which made the skeleton lighter.2

The neural spines on its back vertebrae were broad and plate-like, not forked like in some other sauropods.2

The front chevrons (bones under the tail) were Y-shaped and did not form a closed canal.2

Its femur was long and straight, with greatly expanded ends and a well-developed fourth trochanter for muscle attachment.2

Some scientists think Daanosaurus might actually be a young mamenchisaurid, a group of long-necked sauropods from Asia.1

Mees gevraagde vrae oor Daanosaurus

?How big was Daanosaurus?

Nobody knows for sure because only a young skeleton has been found. Scientists think it was probably similar in size to Bellusaurus, but the adult size is unknown.1

?What did Daanosaurus eat?

It was a plant-eater, like other sauropods. Its spoon-shaped teeth were good for stripping leaves off plants.1 2

?Is Daanosaurus a dinosaur?

Yes, it is a sauropod dinosaur. It lived during the Late Jurassic in what is now China.1

Mite-breker

Mite: Daanosaurus was a giant adult sauropod like many others.

Waarheid: The only known fossil is from a juvenile, so scientists cannot be sure how big it got as an adult.1

Vir dino-kenners

Wetenskaplike naam: Daanosaurus
Benoem deur: Ye et al. 20054
Groep: Langnekke
Familie / klade: Mamenchisauridae4
Klassifikasie: Sauropodomorpha > Sauropoda4
Ouderdom van die rotse: 155 tot 143 miljoen jaar (Kimmeridgian / Tithonian)4
Rotsformasies: Shaximiao4
Lande: China4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: Daanosaurus was named in 2005 by Ye Yong, Gao Yuhui, and Jiang Shan based on a juvenile skeleton found in the Upper Shaximiao Formation of Zigong, Sichuan. The species name zhangi honors Zhang Aiping, former Minister of National Defense.1
Steeds omstrede: Scientists debate whether Daanosaurus is a true brachiosaurid or a juvenile mamenchisaurid, because the only specimen is young and may not show all adult features.1
