Guiyu oneiros (Zhu et al. 2009; late Silurian; V17914) was originally considered the oldest osteichthyan and a member of the lobe-fin clade close to Psarolepis. This revised restoration gives this taxon almost a sea-turtle like appearance, with large pectoral paddles directed posteriorly. Guiyu is transitional from placoderms, but closer to catfish in the LRT. The nose and chin are unchanged inthe catfish, Clarias. |
