a comparison of a monoped and a biped getting up when they fall.
this is the monopod in question: [link]
I used front view to illustrate this because it permitted all legs being visible in both cases.
I propose the most likely position the monoped could be found in after a fall is on its side.
in the biped sequence, i propose this is what it would look like when t-rex was getting up. (minimal forelegs)
In step four of the biped sequence, the hip joint is a ball joint so you see the leg from the side rather than front.
the same is true for step two of the second monoped sequence, but there i argue the joints are being subjected to too much strain or even dislocated.
