Osteology of Batrachuperus londongensis (Urodela, Hynobiidae): study of bony anatomy of a facultatively neotenic salamander from Mount Emei, Sichuan Province, China
A detailed osteological account of B. londongensis is provided based on micro-CT scanning and clearing and staining of multiple specimens from the type locality and a discussion of intraspecific variation related to life-history differences is presented.
A new hynobiid-like salamander (Amphibia, Urodela) from Inner Mongolia, China, provides a rare case study of developmental features in an Early Cretaceous fossil urodele
Comparison of adult with larval and postmetamorphic juvenile specimens provides insights into developmental patterns of cranial and postcranial skeletons in this fossil species, especially resorption of the palatine and anterior portions of thePalatopterygoids in the palate and the coronoid in the mandible during metamorphosis, and post metamorphic ossification of the mesopodium in both manus and pes.
Cranial skeletogenesis of one of the largest amphibians, Andrias japonicus, provides insight into ontogenetic adaptations for feeding in salamanders
The cranial skeletogenesis of the Japanese giant salamander, Andrias japonicus (family Cryptobranchidae), is described for the first time and comparative analyses reveal interspecific differences in cranial skeletal development.
Skeleton in the closet: hidden diversity in patterns of cranial and postcranial ontogeny in Neotropical direct-developing frogs (Anura: Brachycephaloidea)
Results show an overall shared pattern that, as summarized for E. coqui, combines a partial recapitulation of aspects of the ancestral biphasic ontogeny with a profound remodeling that includes lost/novel structures and heterochronic shifts of developmental events.
Comparative osteology of the hynobiid complex Liua‐Protohynobius‐Pseudohynobius (Amphibia, Urodela): Ⅰ. Cranial anatomy of Pseudohynobius
A bone‐by‐bone study of the cranium in the five extant species of Pseudohynobius is provided based on x‐ray computer tomography data for 18 specimens, indicating that the cr skull in each of these species has a combination of differences in morphology, proportions and articulation patterns in both dermal and endochondral bones.
Intraspecific Variation in the External and Skeletal Morphology of Hynobius setouchi Matsui, Okawa, Tanabe et Misawa, 2019 (Amphibia: Urodela: Hynobiidae)
It is found that juveniles had larger heads than those of adults, and most characters were larger in adult males than in females, except for trunk size, and intra- and interspecific comparisons of the external and skeletal characters of salamanders should consider age, sexual, and seasonal differences.
Metamorphosis shapes cranial diversity and rate of evolution in salamanders
Recon reconstructs the cranial evolution of the salamander using geometric morphometric data from 148 species spanning the order’s full phylogenetic, developmental and ecological diversity to demonstrate that life cycle influences cranial shape diversity and rate of evolution.
Descriptive osteology of an imperiled amphibian , the Luristan newt ( Neurergus kaiseri , Amphibia : Salamandridae )
The skull of N. kaiseri has a dense structure, severely ossified elements and a low amount of cartilaginous elements, only in mobile facets.

ABSTRACT Hynobiids are a group of small- to moderate-sized salamanders living primarily in Asia. They are a primitive crown-group clade, with a poor fossil record. Several hynobiid-like taxa have
Osteology of Batrachuperus yenyuanensis (Urodela, Hynobiidae), a high-altitude mountain stream salamander from western China
The species may well have achieved its current distribution in western Sichuan before the drastic uplift of the Qinghai-Tibetan Plateau in Pliocene, indicating that the biogeographic origin and historical evolution of the species are closely associated with the orogeny of the Hengduan Mountains and formation of the Yalong River.
