Marsdenichthys
Extinct genus of tetrapodomorphs / From Wikipedia, the free encyclopedia
Marsdenichthys is an extinct genus of Devonian tetrapodomorph. Fossils have been found from Mount Howitt in Victoria, Australia from strata that are Givetian-Frasnian in age.[1] Mount Howitt is an important site that has been the source of many tetrapodomorph fossils, including Beelarongia and Howittichthys, both of which were first described from the locality.[2][3]

Marsdenichthys was first named in 1985 on the basis of material collected from Mount Howitt. The genus was initially described as a member of the family Eusthenopteridae (now known as the Tristichopteridae), the first known from the southern hemisphere.[4] However, the classification of Marsdenichthys within Tetrapodomorpha has often been debated and there is not yet a consensus on the exact phylogenetic relationships of the genus.[1]
