I'm curious about the energy expenditure in keeping the tail raised the whole time - since the 'tripod' theory of T.Rex posture has dropped in favour of the the bipedal theory, it's keeping a presumably very heavy tail lifted up most of the time - for what purpose? Are there any other examples of animals that do this?

- Tagbert 4y agoI believe that the idea is that the tails of T.rex and other dinosaurs were held up by non-stretching tendons. It would not require active effort. By counterbalancing the head, the high tail would reduce the energy needed to hold the head up.
