Hypobranchials compared to ceratobranchials, that is. *Acanthostega* has 
epibranchials, aÃstopods and anthracosaurs also seem to, but epibranchials 
have not been found in any crown-group tetrapods or even temnospondyls. Reports 
from salamanders or amniotes are simply an outdated misinterpretation dating 
from a time when the hyobranchial apparatus of *Acanthostega* was not yet 
understood (i.e. 1980s or earlier).

My name contains a "nonstandard character" because the standard that bioRÏiv
