A sarcopterygian scale is discovered from Lower Devonian of Zhaotong, Yunnan province, China. It is characterized by its rhombic shape, cosmine and tubercles. The new scale shows traits different from other known sarcopterygian scales through comparison. Sarcopterygians belong to Osteichthyans, and have received wide attention due to their importance in prehistoric evolution pathways. Present evidence indicates that the scale belongs to an unknown dipnomorph, which provides new information on the early evolution of the dipnomorph lineage.
