Shimenolepis granifera is an extinct yunnanolepid placoderm from the Xiaoxi Formation , Li County, Hunan , China. Its age is discussed, while originally considered as late Llandovery , it is later considered to belong to the Ludlow Epoch instead.[1] It was the first described Silurian placoderm, and was the earliest known placoderm until Xiushanosteus was described,[2] known from distinctively ordered plates.

Shimenolepis plates are very similar to the early Devonian yunnanolepid Zhanjilepis , also known from distinctively ornamented plates.[3]
