Bothriolepis

Bothriolepis is a genus of antiarch placoderms. It was widespread and diverse in the middle to late Devonian. 

Bothriolepis lived in environments across every continent including near-shore marine and freshwater settings. Most species of Bothriolepis were  small, benthic, freshwater detritivores. They got nutrients by eating decomposing plant/animal material. They were about  in length.  However, the largest species, B. maxima, had a carapace about  in length. 

Over 70 species are found across the world, but this is also typical of modern bottom dwelling species around today.
