  We present a field theoretical description of quarkyonic matter consisting of
quark, nucleon and ghost fields coupling to mesonic degrees of freedom. The
ghosts are present to cancel over-counting of nucleon states that are Pauli
blocked by the quark Fermi sea. Such a theory becomes an effective field theory
of nucleons at low baryon density, and as such will reproduce nucleonic matter
phenomenology. This theory can accommodate chiral symmetry restoration and the
dynamical generation of a shell of nucleons at the Fermi surface. It is valid
for finite temperature and density. In such a theory, quark-nucleon duality is
accomplished by inclusion of ghost fields so that the nucleons extra degrees of
freedom, that are beyond those of quarks, are compensated by the ghost fields.
