Guiyu is a lobe-finned bony fish from the Pridoli-Early Devonian of China. It was named in 2009 by Min Zhu. It was the earliest lobe-finned fish known, and marked the split between ray-finned fish and lobe-finned fish.


Guiyu was a unique fish. It had the regular lobe-finned fish build (a coelacanth-like fish with a bulky body, fleshy, lobe-like fins, and a small head); however, it had the same scale articulation as early ray-finned fish. Its body would have been covered in scaly skin.


Guiyu's diet remains unknown.
