Acherontiscus is an extinct genus of stegocephalians that lived in the Early Carboniferous (Mississippian era) of Scotland. The type and only species is Acherontiscus caledoniae, named by paleontologist Robert Carroll in 1969. Members of this genus have an unusual combination of features which makes their placement within amphibian-grade tetrapods uncertain. They possess multi-bone vertebrae similar to those of embolomeres, but also a skull similar to lepospondyls. The only known specimen of Acherontiscus possessed an elongated body similar to that of a snake or eel. No limbs were preserved, and evidence for their presence in close relatives of Acherontiscus is dubious at best. Phylogenetic analyses created by Marcello Ruta and other paleontologists in the 2000s indicate that Acherontiscus

  • Acherontiscus is an extinct genus of stegocephalians that lived in the Early Carboniferous (Mississippian era) of Scotland. The type and only species is Acherontiscus caledoniae, named by paleontologist Robert Carroll in 1969. Members of this genus have an unusual combination of features which makes their placement within amphibian-grade tetrapods uncertain. They possess multi-bone vertebrae similar to those of embolomeres, but also a skull similar to lepospondyls. The only known specimen of Acherontiscus possessed an elongated body similar to that of a snake or eel. No limbs were preserved, and evidence for their presence in close relatives of Acherontiscus is dubious at best. Phylogenetic analyses created by Marcello Ruta and other paleontologists in the 2000s indicate that Acherontiscus is part of Adelospondyli, closely related to other snake-like animals such as Adelogyrinus and Dolichopareias. Adelospondyls are traditionally placed within the group Lepospondyli due to their fused vertebrae (although Acherontiscus is an exception among adelospondyls). Some analyses published since 2007 have argued that adelospondyls such as Acherontiscus may not actually be lepospondyls, instead being close relatives or members of the family Colosteidae. This would indicate that they evolved prior to the split between the tetrapod lineage that leads to reptiles (Reptiliomorpha) and the one that leads to modern amphibians (Batrachomorpha). Members of this genus were probably aquatic animals that were able to swim using snake-like movements. (en)

  • Acherontiscus es un género extinto representado por una única especie perteneciente al grupo Lepospondyli, la cual vivió a finales del período Carbonífero en lo que hoy es Escocia. Es el único género dentro de la familia Acherontiscidae. Poseía un cráneo relativamente pequeño y extremidades aparentemente poco desarrolladas. (es)
  • Acherontiscus caledoniae Carroll, 1969 è un tetrapode estinto, appartenente ai lepospondili. Visse nel Carbonifero inferiore - medio (Viséano/, circa 332 - 328 milioni di anni fa) e i suoi resti fossili sono stati ritrovati in Scozia. È considerato il primo tetrapode eterodonte e durofago (Clack et al., 2019). (it)
  • Acherontiscus – monotypowy rodzaj wymarłego płaza z grupy lepospondyli, który żył w karbonie na obszarze dzisiejszej Szkocji. Jest jedynym przedstawicielem rodziny Acherontiscidae. Opisano jeden gatunek – Acherontiscus caledoniae. Miał stosunkowo małą czaszkę i słabe kończyny. (pl)
