Fenghuangopterus was similar to other scaphognathines in its short, blunt skull with a large antorbital fenestra, and widely spaced, vertically oriented teeth (as opposed to the horizontally-oriented teeth of other rhamphorhynchids). Like all known rhamphorhynchids its tail was stiffened by long vertebral extensions. The primary differences between Fenghuangopterus and other scaphognathines reside in its more numerous teeth — eleven in the upper jaw — which extended further back in the jaw than with its relatives, and its earlier time period.[1]
