Fossil Friday


A two legged, very upright, dinosaur skeleton with a long neck, smallish arms and large ribs. About twice as tall as the man in an overall who stands looking up at it. The background is black and the two figures are picked out with a pale light.

That is so cool. I love the upright pose -- tricky to rig!

I imagine so, and one wonders quite how they decided it walked so upright (though, I assume the answer is biomechanics).

The hip joint is the most important, followed by the knee joint and shape of leg bones; the pelvis and foot can also be helpful but are less conclusive. If you're curious, look at the study of stance in the hominid family tree, where it's a crucial factor; those sources often go into more detail than the ones for dinosaurs.
