SULLIVAN, R.M. & FOWLER, D.W. (2006), New specimens of the rare ankylosaurid dinosaur Nodocephalosaurus kirtlandensis (Ornithischia: Ankylosauridae) from the Upper Cretaceous Kirtland Formation (De-na- zin Member), San Juan Basin, New Mexico, New Mexico Museum of Natural History and Science Bulletin, 35: 259-261 [pdf-3mb]

ABSTRACT

New material of the rare ankylosaurid dinosaur Nodocephalosaurus kirtlandensis Sullivan, 1999 is identified and described. Specimens include cephalic osteoderms, a cervical spine, and two caudal vertebrae. The caudal vertebrae are distinct from other known North American ankylosaurids (such as Euoplocephalus tutus), thus reinforcing their taxonomic assignment to N. kirtlandensis. Presently, N. kirtlandensis is known only from the De-na-zin Member of the Kirtland Formation, San Juan Basin, New Mexico.
