However the following differences are notable : in " Eurycleidus " the midline cleft on the bottom surface of the mandibular symphysis is not bordered by the splenials from the back, like in " Atychodracon ".
22.
Because the infratemporal fenestra of " Platyognathus " is very small and the mandibular symphysis extends posteriorly to the level of the seventh to ninth tooth, the genus is thought to be more derived than " Orthosuchus ".

"Aussiedraco " is known from holotype QM F10613, a partial mandibular symphysis housed at the Queensland Museum, recovered from rocks of the Toolebuc Formation, about 70 km east of Boulia, western Queensland, dating to Albian stage.

As their skulls are triangular in shape, with deeply rooted large, serrated teeth and a bulbous, deep mandibular symphysis ( like pliosaurs ), dakosaurs would also have been able to twist feed ( tear chunks of flesh of potential prey ).
25.
These characters include a width of the mandibular symphysis across the swellings of the caniniform teeth that is almost equal to the anteroposterior length of the symphysis and an anterolateral process of the ectopterygoid with an inverted V-shaped ridge on the dorsal surface.
26.
The dentary of the lower jaw expanded in height towards the front ( by the mandibular symphysis ), where it was also flattened, and it had a downwards projection at the tip ( which has been referred to as a " chin " ).
27.
"Tazoudasaurus ", a small sauropod at long, is characterized by rather primitive features such as the prosauropod-like mandible with spatulate and denticle-bearing teeth, lack of a U-shaped mandibular symphysis as other more derived sauropods.
28.
Several features make " Alwalkeria " unique among basal dinosaurs, such as its lack of serrated teeth, the mandibular symphysis being proportionally wider than almost any other known dinosaur, and there is a very large articulation between the fibula and the ankle.
29.
In " Subchilotherium " the mandibular symphysis is much more narrow than in " Chilotherium " . " Acerorhinus " has a strongly constricted nasal base and a mandibular symphysis that is narrow compared to that in " Chilotherium ".
