Hongyu, represented by its type speciesHongyu chowi, is an extinctDevonian lobe-finned fish. About 1.5 m in length, it resembles bothElpistostegalia andRhizodontida, making its phylogenetic placement uncertain.^[1] The type specimen was discovered in theZhongning Formation nearNingxia inChina’sNorth China Block.^[2]
