With greatly elongated fingers the hands are a tantalising find for palaeontologists, but without the rest of the skeleton it is impossible to give an accurate insight into this creature’s life. One possible explanation is that Yixianosaurus lived like a modern day aye-aye. Aye-aye’s also have hands that have impressively long fingers which they use for climbing trees and digging out grubs from inside the trees.
