The illustrations confirm that those are the hypobranchials, not the 
ceratobranchials. And the epibranchials mentioned later are the 
ceratobranchials, not the epibranchials, which are absent throughout the 
tetrapod crown group no matter what that actually is, meaning no matter what 
the phylogenetic positions of the modern amphibians are.

It all started with a 19th-century misinterpretation of the hyobranchial 
apparatus of extant salamanders...
