Invictarx (meaning “unconquerable fortress”) is a monospecific genus of nodosaurid dinosaur from New Mexico that lived during the Late Cretaceous (lower Campanian, 78.5 Ma) in what is now the upper Allison Member of the Menefee Formation. The type and only species, Invictarx zephyri, is known from three isolated, incomplete postcranial skeletons. It was named in 2018 by Andrew T. McDonald and Douglas G. Wolfe. Invictarx shares similarities with Glyptodontopelta from the Naashoibito member of the Ojo Alamo Formation, New Mexico.
