Reptilia - Stegosauridae

Taxonomy
Iguanodon phillipsii was named by Seeley (1869). Its type specimen is SMC B53408, a maxilla (left femur), and it is a 3D body fossil. Its type locality is Priodontognathus type (PROXY), which is in an Oxfordian marine sandstone in the Calcareous Grit Formation of the United Kingdom.

It was recombined as Priodontognathus phillipsi by Lydekker (1904), Huene (1927) and Swinton (1936); it was recombined as Dacentrurus phillipsi by Hennig (1915) and Galton (1985); it was recombined as Omosaurus phillipsii by Hoffstetter (1957); it was recombined as Dacentrurus phillipsii by Kuhn (1964); it was recombined as Lexovisaurus phillipsi by Ulansky (2014) and Ulansky (2014); it was misspelled as Iguanodon phillipsi by Woodward and Sherborn (1890), Seeley (1893), Mansel-Pleydell (1896) and Van Den Broeck (1900); it was considered a nomen dubium by Galton (1983), Galton (1990), Ford (2000), Carpenter (2001), Vickaryous et al. (2004), Galton and Upchurch (2004), Maidment et al. (2008) and Ruiz-Omeñaca et al. (2013); it was recombined as Priodontognathus phillipsii by Seeley (1875), Sauvage (1880), Etheridge (1882), Nopcsa (1901), Galton (1980), Galton (1980), Galton (1981), Galton (1983), Clark (2001), Barrett (2001), Naish and Martill (2008) and Blows and Honeysett (2014).

Diagnosis
ReferenceDiagnosis
P. M. Galton 1980Maxilla with offset anteromedial process fitting into premaxilla and with separate lateral and medial sheets fordally. Eighteen proportionally large maxillary teeth with uniformly enamelled and unornamented lateral and medial surfaces, crowns acute and slightly recurved posteriorly with nine acute denticles anteriorly and seven posteriorly, medial cingulum as two subcrescents separated by a small space with the ventral part curving downward, and the ventral edge bears many fine denticles.
