salamander internasal bone skull anatomy individual variation
Internasal bones have generally been recorded in teleostean and tetrapod fossils, being absent in most extant vertebrates. Presently, there has been one case of the internasal bone discovered in a living salamander, Pseudohynobius puxiongensis (Caudata: Hynobiidae). The second case discovered in living salamanders is reported in this article, which is present in one of five specimens of Hynobius maoershanensis, a species endemic to China. This case is again regarded as individual variation. Thus, the presence of an “internasal bone” may represent intraspecific variation and is thus a misleading taxonomic character.
