Lepidosauromorpha are distinguishable from Archosauromorphs ([[archosaurs]]) by their primitive sprawling gait, which allows for the same sinusoidal trunk and tail movement seen in fish, the sliding "joint" between the coracoids and the sternum (for a longer stride), and their pleurodont dentition. In contrast, Archosauromorphs possess a parasagittal gait, a reduction in their dermal girdle, a reduction and/or loss of the sternum, and a more thecodont dentition.
It is also important to note that, because Lepidosauromorphs are sprawlers, they require less energy to maintain their stance and are thus allowed to remain cold-blooded.
