Daanosaurus
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

Datu dibertigarriak
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

Mitoa: Daanosaurus was a giant adult sauropod like many others.
Egia: The only known fossil is from a juvenile, so scientists cannot be sure how big it got as an adult.1

- 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
