Diagnosis
ReferenceDiagnosis
C. A. Brochu et al. 2012Borealosuchus sharing paired ventral osteoderms, lack of a splenial symphysis, extremely small external mandibular fenestra, and a short dentary symphysis, extending no further back than the fourth dentary alveolus, with B. wilsoni. Lacks the deep sulci between first three dentary alveoli that characterize B. wilsoni. Surangular-angular suture passes ventrally along mandibular fenestral margin and dentary does not pass ventral to the fenestra in lateral view.
