Guiyu is an extinct genus of bony fish, and is the earliest known bony fish from the fossil record. It lived during the Late Silurian (419 million years ago) in China and was 33 cm long. It has the combination of both actinopterygian and sarcopterygian features, although analysis of the totality of its features place it closer to Sarcopterygii (lobe finned fishes).
