Early Devonian sarcopterygians

Kenichthys
Kenichthys is a genus of sarcopterygian fish from the Devonian period, and a member of the clade Tetrapodomorpha. The only known species of the genus is Kenichthys campbelli (named for the Australian palaeontologist Ken Campbell), the first remains of which were found in China in 1993. The genus is important to the study of the evolution of tetrapods due to the unique nature of its nostrils, which provide vital evidence regarding the evolutionary transition of fish-like nostrils to the tetrapod choanae.
Tungsenia
Tungsenia is an extinct genus of lobe-finned fish known from the early Devonian Posongchong Formation of Yunnan, South China. It is the earliest and most basal tetrapodomorph known, having a mixture of traits of tetrapodomorphs and basal dipnomorphs. This not only is present in the skull itself but also in the brain which has features much more similar to dipnomorphs than to other early tetrapodomorphs. Due to this, along with a more derived mandible, it is likely that the jaw of tetrapodomorphs evolved earlier than other parts of the head. There is only one species of the genus known; T. para
Porolepis
Porolepis is an extinct genus of porolepiform sarcopterygian fish, from the Early Devonian Dniester Series of Ukraine, which is rich in Porolepis remains, and also the Nellen Koepfchen Beds of Germany. It lived alongside the dubious lophotrochozoan Macrodontophion. It was first described in 1858 but Porolepis was not named as a sufficient species until 1891.
Qingmenodus
Qingmenodus is a genus of prehistoric lobe-finned fish. Fossils of Qingmenodus were found in China and date back to the Early Devonian period. Qingmenodus reveals the first well-ossified otoccipital braincase in onychodonts. Palaeontologists believe that Qingmenodus was one of the oldest onychodont fish.
