Fossil representation: Holotype an almost complete individual. At least one another specimen known.
Leptopleuron was a genus or procolophonid reptile that lived in Scotland during the Late Triassic. The exact diet of Leptopleuron is uncertain, though procolophonids in the late Triassic seem to be more herbivorous than earlier procolophonids were more insectivorous.
