Just sharing some concept sketch ideas for a clay sculpture project I plan on doing some time soon.

Number I~ is hominid in design. This forelimb would have utilitarian use as a bipedal creature
Nuber 2~ is quadripedal, and also semi-aquatic in design.
Number 3~ is a wing arm for crawling and flight. It's also flexible enough to rotate the joints for climbing cliffsides and large trees.
Number 4~ is similar to predatory mammals.
Number 5~ is excellent at digging into burrows.
