Reptilia

Taxonomy
Thyreophoroidea was named by Nopcsa (1928). It was considered monophyletic by Maidment et al. (2008).

It was reranked as the superfamily Thyreophoroidea by Huene (1934) and Huene (1934).

It was assigned to Orthopoda by Nopcsa (1928); to Ornithopoda by Nopcsa (1929); to Ornithischia by Huene (1934) and Huene (1934); to Thyreophora by Sereno (1986); and to Thyreophora by Maidment et al. (2008).

Diagnosis
ReferenceDiagnosis
B. F. Nopcsa 1928teeth with multicusped margin and striated crown, more or less complete dermal armour.
S. C. R. Maidment et al. 2008Scelidosaurus, Ankylosaurus, their most recent common ancestor and all of their descendants (Sereno 1986).

Unambiguous synapomorphies:
• Supraorbitals form the dorsal rim of the orbit
• Anterior caudal neural spine height is greater than the height of the centrum (reversed in Sauropelta)

Additional synapomorphy using ACCTRAN:
• Presence of U-shaped cervical collars composed of keeled scutes (reversed in Stegosauria)

Additional synapomorphies using Delayed Transformation (DELTRAN):
• Quadrate condyle angled strongly ventromedially in posterior view (equivocal in basal thyreophorans)
• Transverse processes of dorsal vertebrae project at a highangle to the horizontal (equivocal in Emausaurus; reversed in Gigantspinosaurus)
• Large horizontal lateral enlargement of the ilium present (equivocal in Emausaurus)
• Supra-acetabular flange present (equivocal in Emausaurus; reversed in Ankylosauria)
