ABSTRACT We present new and well-preserved giant salamander material from the Miocene of the Grytsiv locality, Ukraine. Disarticulated skull and postcranial bones from two individuals are described as a new taxon, Ukrainurus hypsognathus, gen. et sp. nov. U. hypsognathus is characterized by poorly ossified bone tissues, relatively inflexible mandibles, a high dentary, a crista on the lingual surface of the dentary, a pars dentalis of the dentary that is composed of a dental lamina and a… 
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.
A unique dentary suggests a third genus of batrachosauroidid salamander existed during the latest Cretaceous in the western USA
An incomplete salamander dentary (AMNH FARB 22965) described herein from the upper Maastrichtian Lance Formation, Wyoming, USA, exhibits a puzzling suite of features. Four features—a prominent bony
The last Palaeoproteus (Urodela: Batrachosauroididae) of Europe
A new species is described, Palaeoproteus miocenicus, from the early late Miocene of Austria and Ukraine, representing the youngest record of the family Batrachosauroididae from the Neogene of Europe and expands the temporal range of the genus by at least 30 million years and enlarges the palaeogeographic distribution of the species into Eastern Europe.
A new late Miocene Anomalomys species from western Ukraine with implications for the diversity and evolution of anomalomyid rodents in Eastern Europe
ABSTRACT Anomalomyid rodents first appeared in the fossil record of Europe in the early Miocene being represented by three small-sized species of the genus Anomalomys (A. aliveriensis, A. minor, and
Pronounced Peramorphosis in Lissamphibians—Aviturus exsecratus (Urodela, Cryptobranchidae) from the Paleocene–Eocene Thermal Maximum of Mongolia
Aviturus exsecratus is not only a cryptobranchid with distinctive peramorphic characters, but also the first giant salamander with partially terrestrial (amphibious) lifestyle, and the morphology of the vomers and dentaries suggests the ability of both underwater and terrestrial feeding.
Giant salamander from the Miocene of the Mecsek mountains (Pécs-Danitzpuszta, southwestern Hungary)
The Late Miocene fossil locality Pécs-Danitzpuszta (Mecsek Mts., Hungary) has yielded cranial and postcranial bones of giant salamanders. Based on taxonomical studies, these relatively
A new proteid salamander (Urodela, Proteidae) from the middle Miocene of Hambach (Germany) and implications for the evolution of the family
A phylogenetic analysis recovered the new taxon in an early‐branching position within Proteidae, suggesting the presence in Europe of a second proteid lineage, currently known only in the middle Miocene, that appears unrelated to the Mioproteus–Proteus clade.
Neogene amphibians and reptiles (Caudata, Anura, Gekkota, Lacertilia, and Testudines) from the south of Western Siberia, Russia, and Northeastern Kazakhstan
The Neogene assemblage of Western Siberia was found to be dominated by groups of European affinities, such as Palaeobatrachidae, Bombina, Hyla, Bufo bufo, and a small part of this assemblages included Eastern Palaearctic taxa.


Re-Evaluation of Mynbulakia Nesov, 1981 (Lissamphibia: Caudata) and Description of a New Salamander Genus from the Late Cretaceous of Uzbekistan
The structure of the atlas, the absence of spinal nerve foramina in the trunk and anterior caudal vertebrae, and the presence of unicipital transverse processes on the trunk vertebraes suggest that N. mynbulakensis may be a member of the Cryptobranchoidea.
This phylogeny and fossil occurrences imply that the characteristic atlanto–cranial joint and elongate trunk and the unique vertebromuscular complex of amphiumids were established by the Cretaceous–Tertiary boundary, while elongation of the snout and associated cranial modifications seen in living amphiums appeared after the late Paleocene.
Land salamanders of the family Hynobiidae from the Neogene and Quaternary of Europe
A new extinct genus with two new species of land salamanders of the family Hynobiidae, from the Late Miocene of Polgardi (MN13) and from the Lower Pleistocene of Betfia IX/C (MQ1), Romania, is described.
Comparative skull osteology of Karsenia koreana (Amphibia, Caudata, Plethodontidae)
The analysis of the anatomy of the new Asiatic lineage illuminates some potential mechanisms underlying adaptive morphological evolution within the Plethodontidae.
Earliest known crown-group salamanders
The discovery of well-preserved Middle Jurassic salamander from China constitutes the earliest known record of crown-group urodeles (living salamanders and their closest relatives) and provides evidence to support the hypothesis that the divergence of the Cryptobranchidae from the Hynobiidae had taken place in Asia before the Middle Jurassic period.
Albanerpetontid amphibians from the Upper Cretaceous of Middle Asia
We review the fossil record of Asian albanerpetontids. The three dentaries previously attributed to the two species of. Nuhtsurus Nessov, 1981 (lower Cenomanian and Coniacian, Uzbekistan) are from
Early tooth transformation in the paedomorphic Hellbender Cryptobranchus alleganiensis (Daudin, 1803) (Amphibia: Urodela) *
Dentition of the upper and lower jaws and the palate of three larvae of different sizes and one adult specimen of the paedomorphic Cryptobranchus alleganiensis is described, finding no signs of dental laminae accompanying the coronoids and the palatines, which explains the total absence of teeth on these bones.
Reduced genetic variation in the Japanese giant salamander, Andrias japonicus (Amphibia: Caudata).
Phylogeny, evolution, and biogeography of Asiatic Salamanders (Hynobiidae).
It is hypothesized that the interior desertification from Mongolia to Western Asia began approximately 50 Mya; the Tibetan plateau experienced rapid uplift approximately 40 Mya and reached an altitude of at least 2,500 m; and the Ailao-Red River shear zone underwent the most intense orogenic movement approximately 24 Mya.
Osteological Peculiarities of Bufo brongersmai (Anura: Bufonidae) and Their Possible Relation to Life in an Arid Environment
The presence in adult individuals of a rather-large maxillary fontanella, which late in ontogeny is reduced to a few foramina, has not been observed in other species, seems likely related to the rapid larval development that allows B. brongersmai to achieve higher reproductive fitness than other species in the highly ephemeral waters of the rocky, arid environment it inhabits.
