Because Epidendrosaurus is more similar to advanced birds in some arboreal features than to Archaeopteryx, we suggest that the initial appearance of tree-adaptation in theropods was probably not directly related to flight but to other functions, such as seeking food or escaping from predators.
This sounds very familiar...
The specimen is about the size of a house sparrow (Passer domesticus) and obviously a juvenile individual as evidenced by many distinctive juvenile features, such as the incomplete ossifications of articular surface, presence of grooves on some limb bones and less well- defined extremities of postcranial long bones...
Such a tiny young one.
Epidendrosaurus ningchengensis gen. et sp. nov.
There are at least nine cervical vertebrae preserved in articulation, with the anterior ones longer than the posterior. The total length of the tail is estimated to be 6-7 times as long as the femur.
