Field notes
About Ferganasaurus
What it was like
Ferganasaurus was a long-necked, four-legged plant eater, known from part of a skeleton. It was similar to Rhoetosaurus from Australia.
Its world
It lived in the Middle Jurassic in what is now Kyrgyzstan. Its bones come from the Balabansai Formation, where it shared the land with the hunter Alpkarakush.
How it was found
Alifanov and Averianov named Ferganasaurus in 2003, from a single find. The bones had been dug up decades earlier.

Lived alongside
Found in the same rock formations
A rock formation can hold fossils laid down millions of years apart, so not every animal here met Ferganasaurus.
The evidence
The science behind Ferganasaurus
Which parts of the picture come from its own bones, and which come from its relatives.
From its own fossils
- The type skeleton includes back and tail vertebrae, hip bones and limb bones.
- Its lost hand bones were recorded in drawings, with upright hand supports arranged in a semicircle and short, stout finger bones.
Borrowed from relatives
- Its missing head is restored by comparison with Bagualia, and its missing hindfeet with Camarasaurus.
Still unknown
- The shape of its skull, the length of its neck and whether the recorded claws came from the hands or feet.
- Its exact position in the sauropod family tree, which differs between studies.
- Its skin texture and color.
