Diagnosis
ReferenceDiagnosis
C. A. Sidor et al. 2021Palatal dentition extremely reduced; palatine and pterygoid bosses ridge-like and oriented nearly anteroposteriorly; pterygoid midline suture absent; palatal exposure of jugal extends far anteriorly between maxilla and ectopterygoid; tall supraorbital boss (over 50% of orbit height), which is triangular in lateral view and has recessed area on its lateral surface; posterodorsal margin of lateral temporal fenestra with medially recessed shelf. Isengops can be distinguished from other burnetiamorphs by a taller nasal ridge than in Lemurosaurus (but one that is similarly unpachyostosed) and a supratemporal “horn” more robust than in Lobalopex, but not extremely pachyostosed as in Bullacephalus or Burnetia.
