Phyllolepis (from the Greek roots for ‘leaf’ and ‘scale’)[1] is the type genus of Phyllolepida, an extinct taxon of arthrodire placoderm fish from the middle to late Devonian.[2] The species of Phyllolepis, themselves, are restricted to the Famennian-aged freshwater strata of the Late Devonian, around 360 million years ago. Fossils of this genus have been found primarily in Europe and North America.[2] The end of the Devonian saw them disappear in a mass extinction.
Phyllolepis lived in freshwater environments, possibly rivers and streams. As with all other known phyllolepids, Phyllolepis were presumed to have been blind, bottom-dwelling predators that detected prey through sensory organs in the surface grooves of their armor plates (which gave their plates a distinctive "wooden surface" appearance).
