Phlegethontia

Phlegethontia is a genus of lepospondyl amphibian from the Carboniferous and Permian periods of Europe and North America.[1]

Phlegethontia is an aïstopod, a group of legless snake-like amphibians. It was about 1 metre (3.3 ft) long, and possessed a lightly built skull with many openings, unlike some earlier relatives.[2]

Life reconstruction of Phlegethontia longissima

"Dolichosoma" longissima, named by Antonin Fritsch in 1875, has been reassigned to the genus Phlegethontia and is now considered to be P. longissima.[3][4] "Dolichosoma"has been considered to be a nomen nudum because the holotype was inadequately described through a layer of matrix by Thomas Henry Huxley in 1867.[5][6]
