Kenichthys
Encyclopedia
Kenichthys was an ancient tetrapodomorph, a lineage that included tetrapods. It was one of the most primitive tetrapodomorphs. This specific genus is important because it contains a primitive choana
on its upper lip, giving it a cleft palate-like structure. Interestingly, the migration of this opening would have blocked arteries in the palate
; it is possible that these blood vessels shifted position during evolution. The holotypes include well preserved bones which were found in China

The palate is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. A similar structure is found in crocodilians, but, in most other tetrapods, the oral and nasal cavities are not truly separate. The palate is divided into two parts, the anterior...
