Partial skeleton with skull.

Characterized by a skull about threefourths as wide as long, with a toothed premaxilla and an infratemporial fenestra that is hidden below a coudoventrally expanded jugal- quadratojugal-postorbital.

The latter condition is unique whitin the Nodosauridae and differs from the diagnostic ankylosaurid condition in which dermal plates cover the infratemporal fenestra
