Diagnosis
ReferenceDiagnosis
T. S. Marinho and I. d. S. Carvalho 2009A Sphagesauridae bearing two premaxillary teeth, the second ones are hypertrophied caniniforms; posterior maxillary teeth present the major crown axis obliquely oriented with few large tubercles disposed in one lingual keel (Fig. 4); lower jaw is narrow and elongated at the symphyseal region; the first dentary teeth facing anteriorly; fourth dentary teeth slightly flattened laterally and have anterior keels; the fifth dentary teeth has the major crown axis obliquely oriented with the tuberculated keel facing the labial margin, and occluded behind the third maxillary teeth; basioccipital-basisphenoid suture marginate the foramen intertympanicum posteriorly; foramen intertympanicum in the basisphenoid; basioccipital-basisphenoid suture marginate the lateral Eustachian foramina posteriorly and laterally; lateral Eustachian foramina aligned to the foramen intertympanicum (Fig. 3); antorbital depression divided into two parts: a smooth and deeper and an ornamented and shallower one; body armor with two distinct parts: a cervical shield and a banded dorsocervical section; hexagonal osteoderms compose most of the cervical shield.
