Glyptodontopelta mimus

Reptilia - Nodosauridae

Taxonomy

Glyptodontopelta mimus was named by Ford (2000). Its type specimen is USNM 8610, an osteoderm (co-ossified pelvic osteoderms (portion of pelvic shield), isolated thoracic and pelvic osteoderms, osteoderm fragments from cervical/pectoral rings), and it is a 3D body fossil. Its type locality is 1 mile southwest of Ojo Alamo Store (USNM), which is in a Maastrichtian terrestrial horizon in the Ojo Alamo Formation of New Mexico.

It was considered a nomen dubium by Carpenter (2001) and Vickaryous et al. (2004).

Synonyms

Edmontonia australis was named by Ford (2000). Its type specimen is NMMNH P-25063, an osteoderm, and it is a 3D body fossil.

It was considered a nomen dubium by Vickaryous et al. (2004); it was synonymized subjectively with Glyptodontopelta mimus by Burns (2007), Burns (2008), Jasinski et al. (2011), Arbour et al. (2014) and Arbour and Currie (2016).

Diagnosis

Reference	Diagnosis
M. E. Burns 2008	A nodosaurid differing from the Late Cretaceous North American nodosaurids (Edmontonia and Panoplosaurus) and ankylosaurids (Ankylosaurus, Euoplocephalus, and Nodocephalosaurus) in: (1) the dorsal surface of the osteoderms possess a distinctive dendritic pattern consisting of vascular furrows radially directed away from the keel coupled with randomly distributed small pits and pores; and (2) rectangular medial cervical osteoderms with rounded edges and a keel medial in position.
V. M. Arbour and P. J. Currie 2016	Uniquely amongst ankylosaurs, osteoderms have distinctive dendritic pattern consisting of vascular furrows radially directed away from the keel, with randomly distributed small pits and pores.
