Meemannia is a genus of extinct bony fish from the early Devonian period. It was initially classified as a lobe-finned fish; however, a restudy conducted by Lu et al. (2016) indicates that it was actually an early-diverging ray-finned fish.[1] It was found in Yunnan, China. As preserved, it consists mainly of skull roofing bones and a partial otic region of the braincase. Its anatomy is unique in a number of features that resemble ray-finned fishes (Actinopterygii), and more generalized jawed vertebrates.
It was described in the May 4, 2006 edition of Nature, and named after Meemann Chang.[2]
