![]() Other features of the craniofacial skeleton of S. ![]() ![]() Functional and comparative assessment of the feeding apparatus strongly indicates a predominantly if not exclusively herbivorous diet. Assessment of both external and internal morphological features indicates a habitual head posture in which the preorbital portion of the dermal skull roof was tilted downward at an angle of ∼45°. The two most complete and well-preserved specimens differ substantially in several size and shape variables (e.g., projections, angulations, and areas of ornamentation), suggestive of sexual dimorphism. clarki, including a portion of the hyobranchial apparatus. In this report, we provide a detailed description of the entire head skeleton of S. clarki one of the best and most completely preserved among all known basal mesoeucrocodylians. Collectively, these six specimens represent all elements of the head skeleton except the stapedes, thus making the craniofacial skeleton of S. clarki is now known from five additional specimens that preserve portions of the craniofacial skeleton. ![]() Originally described on the basis of a single specimen including a remarkably complete and well-preserved skull and lower jaw, S. Simosuchus clarki is a small, pug-nosed notosuchian crocodyliform from the Late Cretaceous of Madagascar.
