An articulated pes from a small parvicursorine alvarezsauroid
(Dinosauria: Theropoda) from Inner Mongolia, China.

A near complete and articulated parvicursorine pes, referred to
Linhenykus, is described. This is one of the first foot skeletons to
be described for a derived alvarezsaur and provides new information on
the first digit of the pes. The evolution of a laterally directed
flange of the anterior face of the distal third metatarsal in
arctometatarsalian taxa is discussed.
