Secretary birds like to rest in the grass, and ratites seem to have two 'sitting' positions: a conventional belly rest and a rather amusing one where they 'sit' on their ankles (though there's pictures of storks, herons, egrets, and a secretary bird doing this as well). Lastly, tyrannosaurs appear to have put weight on their pubic bone to sit. | |

Humans have specific adaptations for sitting (namely padded backsides), indicating that sitting is quite prominent in our evolutionary history. I see none of those adaptations in therapods or birds. Most birds specifically have adaptations to ligaments that allow for muscle-free grasping of perches. I'm not sure if therapods have similar adaptations for effort-free standing (presumably some of the larger ones would as they'd have trouble lying and getting up). | |
