- Another key trait is the choana.
- They define the Eryopoidea as all Euskelia in which the choana are relatively rounded and the iliac blade vertical.
- Each sinus opens into the roof of the nasal cavity via apertures on the posterior wall of the sphenoethmoidal recess directly above the choana.
- The large palatal roof component of the vomer in " Thrinaxodon " is just dorsal to the choana, or interior nasal passages.
- In the palate region of the skull, the anterior process of the vomer ventrally overlies the premaxilla at the anterior margin of the choana.
- However, " Fruitachampsa " can be linked to shartegosuchids on the basis of similarities in the structure of the front of the palate and the choana.
- The debate was further complicated by the fact that lungfishes, another group of sarcopterygian fish, also possess a choana with a different form to that of tetrapodomorphs.
- The lateral surface of this plate forms part of the pterygoid fossa, the medial surface constitutes the lateral boundary of the choana or posterior aperture of the corresponding nasal cavity.
- ""'Brillanceausuchus " "'is an extinct genus of homoplasic, thus making the evolution of the position of the choana within crocodilians more complex than previously thought.
- After insertion balloon is inflated with 5-10 ml of saline . The bulb is inflated with saline and pulled forward so that choana is blocked and then an anterior nasal balloons are also available.
- Various suggestions had been put forward including that the choana was homologous to either the posterior or anterior nostril of non-tetrapods, that it had budded off from one of these passages, or that it was an entirely novel form, unrelated to either of the other nostrils.
- Through convergent evolution, lungfishes have evolved internal nostrils similar to the tetrapods'choana, and a brain with certain similarities to the lissamphibian brain ( except from the Queensland lungfish, which branched off in its own direction about 277 million years ago and has a brain resembling that of the Latimeria ).
- The character state of the nostrils of " Kenichthys " demonstrates that the vertebrate choana did in fact evolve by migration of the posterior external nostril around the jaw and up onto the roof of the mouth . " Kenichthys " suggests that this migration took place on the route between the premaxilla and the maxilla.
- On Long's 1986 expedition to Gogo the first relatively complete skull of " Gogonasus " was found by Chris Nelson and after being prepared solved a scientific controversy by showing that the inner large fangs of the coronoid bones did not insert into the choana of the palate ( Long 1988 ) as had been suggested by Rosen et al . ( 1981 ) for " Eusthenopteron ".
- Such evidence is now available : a small lobe-finned fish called " Kenichthys ", found in China and dated at around 395 million years old, represents evolution " caught in mid-act ", with the maxilla and premaxilla separated and an aperture & mdash; the incipient choana & mdash; on the lip in between the two bones . " Kenichthys " is more closely related to tetrapods than is the coelacanth, which has only external nares; it thus represents an intermediate stage in the evolution of the tetrapod condition.
