What the rig can and cannot do

51 skinned bones, all from a humanoid template. No tail chain, no wing bones, no jaw, no neck joint in the skin.
Tail is one leaf bone (R_ToeBase) plus the legs. The travelling wave down the coil is not bones at all, it is a rotation applied to the rest positions before skinning.
Back blades share Waist and both clavicles with the arms, so they cannot be sprung on their own either. Same trick.
Jaw has no bone. It swings around a measured hinge in the vertex shader. It cannot close: the upper fangs interlock into the lower jaw with only 2.5 degrees of clearance, so closing would drive the jaw through them.
Joint transforms were missing in the export, so every bone sat at the origin. They were rebuilt from the inverse bind matrices before this page could animate anything.
