Fun facts
The only known bone is a complete right thigh bone (femur) that is 180 centimetres (5.9 feet) long.1
Scientists think it was about 30 metres (98 feet) long, which would make it one of the longest dinosaurs known.1
Its femur has a deep U-shaped groove between the joints at the knee, which is a special feature.3
The fourth trochanter, a bump on the thigh bone where muscles attach, is mound-shaped and sits above the middle of the bone.3
Fushanosaurus lived about 161 to 155 million years ago, during the Oxfordian age of the Late Jurassic.2
It was first thought to be a titanosauriform, but later studies suggest it might be a mamenchisaurid, a group known for very long necks.1

Myth buster
Myth: Some people think Fushanosaurus was a titanosauriform, a type of sauropod.
Truth: Scientists now think it might actually be a mamenchisaurid, because the features that suggested titanosauriform are also found in other sauropods.1
