Anhuilong

Anhuilong is known only from a left humerus, ulna, and radius, the bones of its upper arm and forearm.12

Its name means 'Anhui dragon' after the Chinese province where it was found.1

Anhuilong lived during the Middle Jurassic, about 174 to 162 million years ago.3

It belongs to a group of sauropods called Mamenchisauridae, which were common in Asia during the Jurassic.2

Scientists think Anhuilong was a close relative of another mamenchisaurid called Huangshanlong, which was also found in eastern China.2

The arm bones of Anhuilong were slender compared to those of its relative Huangshanlong.2
