       Named after a tributary of the River Styx from Ancient Greek mythology,‭ ‬Acherontiscus was a small lepospondyl that lived in the‭ ‬area that‭ ‬what would become Scotland‭ ‬back‭ ‬in the Carboniferous period.‭ ‬Acherontiscus is also the type genus of its own group,‭ ‬the Acherontiscidae.‭ ‬Acherontiscus is noted for having a long body but proportionately small limbs.‭ ‬This may have been an evolutionary development that allowed Acherontiscus to pass through and amongst narrow obstacles in search of small prey.
