Diplovertebron is an extinct genus of Anthracosauria (stegocephalian) that lived in the Late Carboniferous period (Moscovian) (300 million years ago). Diplovertebron was a medium-size animal, 60 cm in length. Diplovertebron punctatum inhabited European Carboniferous swamps (nowadays Czech Republic), where it caught fish and smaller amphibians. Another, closely related species, lived in the Pennsylvanian period in North America. Diplovertebron is an important link in evolution, because its body structure resembled that of a reptile.
