Did deinosaurs even have a glutius maximus?
I thought that in reptiles, the big leg retractor muscle was the
I also figured that this was one of the big reasons why most mammals
rather small, thin tails compared to body size
I don't know; GOOD question! I'm sure someone on this list DOES
know & will (hopefully) chime in here. :-) I believe you are correct about
lizards & crocodiles at least. As far as tails, I think most mammals could
support a more robust tail than they actually have. Perhaps function has
downsized most mammal tails?
Still, it's difficult for me to picture a large saurapod actually
galloping. I think the point about ankle flexion (or rather, the lack of
it) is pertinent there. "Fast walking", which is what elephants seem to be
doing seems a better match to saurapod anatomy. And I'm not convinced adult
saurapods needed to run from anything (I know I asking for it here! :-)).
About ankle flexion: did prosaurapods have more flexible ankles
than later saurapods?
