Phymolepis
Phymolepis is an extinct genus of yunnanolepidid placoderm from the Early Devonian of China.[1] The type species, P. cuifengshanensis, was named by Zhang Goroui in 1978[1][2] and was re-evaluated in 2018,[3] while a second species, P. guoruii, was named and described in 1996.[4]

The holotype of P. cuifengshanensis is IVPP V4225.3, a nearly complete trunk shield, and it was found in the Xitun Formation, near Cuifengshan.[2] The paratype is IVPP V4425.6, a posterior median dorsal plate, and several other specimens of varying completeness have also been referred to Phymolepis,[3] with some specimens also being recovered from the Xishancun Formation.[4]
