Jaekelocarpus is a genus of mitrate stylophoran known from the Morrowan age of the Golf Course Formation, southern Oklahoma, US. [1] It possessed two billaterally symmetrical complexes of four internal bars. The morphological similarity of these structures to the gill bars of cephalochordates and enteropneusts is considered a likely indicator of their homology. [2] [3]
