Bothriolepis

Bothriolepis (Greek: "pitted scale" or "trench scale") is a widespread, abundant and diverse genus of antiarch placoderms that lived during the Middle to Late Devonian period of the Paleozoic Era. Historically, Bothriolepis resided in an array of paleo-environments spread across every paleocontinent, including near shore marine and freshwater settings.[1] Most species of Bothriolepis were characterized as relatively small, benthic, freshwater detritivores(organisms that obtain nutrients by consuming decomposing plant/animal material), averaging around 30 centimetres (12 in) in length.[2] However, the largest species, B. rex, had an estimated bodylength of 170 centimetres (67 in). Although expansive with over 60 species found worldwide,[3] comparatively Bothriolepis is not unusually more diverse than most modern bottom dwelling species around today.[4]
