  This may merely be the argument because the authors have assumed that the 
specimen belongs to a "bird"-like animal, and therefore the tarsals are assumed 
to be fused to one another/other limb bones and an adult. This is an impression 
that is leading enough. The vertebrae do appear to have closed neurocentral 
sutures, and that's pretty telling.
