The humerus/femur ratio of _Eosinopteryx_ is 0.8 - pretty much the
same as _Microraptor_.  But lower than _Anchiornis_ (1.04) and
_Archaeopteryx_ (1.1-1.2).

The manus/femur of _Eosinopteryx_ is about 1.2 - actually a bit higher
than _Microraptor_ (1.06).  But lower than _Anchiornis_ (1.55) and
_Archaeopteryx_ (1.4-1.6).
