It is distinguished from other nodosaurid ankylosaurs by ratio of skull length width about 1.4 : 1; the parietal area flat; the posterior margin and the lateral margins lateral to the orbits straight in dorsal view; the widths of humerus almost similar in both the proximal and dostal ends, the attachements of M. latissimus dorsi and M. teres major on the posterior surface of the proximal end of humerus are concave, and the shaft of the ischium straight.
