Jaekelocarpus is a genus of mitrate stylophoran known from the Morrowan age of the Golf Course Formation (southern Oklahoma, USA). They 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.
