Raphus skeleton

I don't know if there are any reliable, anatomically correct skeletal drawings of a complete dodo skeleton, so I decided to do one. It is based on the London, Vienna and Oxford specimen. I tracked out the London specimen for a maximum precision regarding proportions and shape of the bones. However, I still suck at drawing accurate vertebral bodies and ribcages without being able to have a look at them in real life. I have a skeleton of Columba palumbus at home, but it is only distantly comparable to that of its large relative.
