We construct exotic contact Anosov flows that are topologically distinct from all previously known examples and have « exponentially more » closed orbits. For a maximal isotropic foliation of a contact form we present a sequence of Godbillon-Vey invariants that lend themselves to easy proofs of rigidity results when applied to the dynamical foliations of a contact Anosov flow.
