Kenichthys campbelli (Chang and Zhu 1993; Zhu and Ahlberg 2004; Early Devonian, 395 mya) was originally considered a basal sarcopterygian demonstrating the migration of the exit nostril to the jaw rim on its way to the palate to become the choana. Here Kenichthys nests basal to the Stensioella through Latimeria (coelocanth) clade.

Youngolepis praecursor (Chang and Yu 1981; Early Devonian 410 mya; less than 30 cm in length estimated). Distinct from other lungfish, Youngolepis had large eyeballs, fused several skull bones together and retained both a large vomer fang and elongate maxilla. Note the in-naris and out-naris both were ventral in exposure.
