tibia

This arrangement suggests rapid movement.

Tibia and fibula.

In Pterodactylus longirostris, the tibia is slender, more than a fifth longer than the femur.

A crest is never developed at the proximal end, like that seen in the guillemot and diver and other water birds.

Sorry about that.

Shinbone and Sam?

Nah, he wasn't invited.

Didn't get invited.

So the knees are kind of knocked in.

Tibia is rotated out.

And if we understand some things about the knee, it's like, okay, well, for my knee to bend, I probably want the opposite of that, right? I probably want to get relative external rotation of the hip, relative, and I probably want to get relative internal rotation of the tibia.

We can look up some things like the scroll mechanism, but for me to bend my knees, I probably want these two things to occur.
