Notorhizodon

Notorhizodon is a genus of prehistoric lobe-finned fish which lived during the Devonian period ( Givetian stage, about 385 - 391 million years ago). It belonged to the family of Tristichopteridae fishes. Fossils have been found in Antarctica and described by Young et al. in 1992. Notorhizodon probably lived in freshwaters.
