ABSTRACT North American Late Cretaceous salamanders are principally known by isolated atlantes and trunk vertebrae. Here I describe a new genus and species of fossil salamander, Paranecturus garbanii, gen. et sp. nov., based on these elements from the lower portions of the Hell Creek Formation (Maastrichtian), Garfield County, northeastern Montana, U.S.A. It is diagnosed by a unique combination of character states that include the presence of an alar-like process of the atlas and a groove on…

A new proteid salamander from the early Oligocene of Romania with notes on the paleobiogeography of Eurasian proteids
TLDR
A new species of proteid salamander from the early Oligocene of Romania is described representing the geologically oldest member reported from the Cenozoic of Eurasia and appears to be closely allied with M. caucasicus and M. wezei, the only living European proteid.
New sharks and other chondrichthyans from the latest Maastrichtian (Late Cretaceous) of North America
Abstract. Cretaceous aquatic ecosystems were amazingly diverse, containing most clades of extant aquatic vertebrates as well as an array of sharks and rays not present today. Here we report on the…
A new proteid salamander (Urodela, Proteidae) from the middle Miocene of Hambach (Germany) and implications for the evolution of the family
TLDR
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.
The last Palaeoproteus (Urodela: Batrachosauroididae) of Europe
TLDR
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 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…

Phylogeny and systematic history of early salamanders
TLDR
While this study has not resolved the relationships between salamander families it has allowed a deeper understanding of the data, and assesses the confidence with which the placement of key fossils can be made in a new way.

THE FOSSIL SALAMANDER PROAMPHIUMA CRETACEA ESTES (CAUDATA; AMPHIUMIDAE) AND RELATIONSHIPS WITHIN THE AMPHIUMIDAE
TLDR
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.
Parrisia neocesariensis, a new batrachosauroidid salamander and other amphibians from the Campanian of eastern North America
TLDR
The Ellisdale site has produced the first representative fossil amphibian specimens from the Cretaceous of eastern North America, and a previously undescribed genus of batrachosauroidid salamander, herein described as Parrisia neocesariensis gen. et sp.
Late Jurassic salamanders from northern China
TLDR
The discovery of an extraordinary sample of salamander fossils from the Upper Jurassic of China is reported, providing compelling evidence for an Asian origin of Recent salamanders, as well as for an extensive and early radiation of several major lineages.
Revision of Piceoerpeton Meszoely (Caudata: Scapherpetontidae) and description of a new species from the late Maastrichtian and ?early Paleocene of western North America
The scapherpetontid salamander Piceoerpeton is known from the latest Cretaceous to middle Paleogene of North America and was the last surviving member of that paedomorphic family. A suite of…

Frogs and salamanders from the Upper Jurassic Morrison Formation (Quarry Nine, Como Bluff) of North America
ABSTRACT Previously undescribed frog and salamander bones from the Morrison Formation, at Quarry Nine, Como Bluff, Wyoming, are reported. One anuran ilium is diagnostically discoglossid and forms the…
Revision of Habrosaurus Gilmore (Caudata; Sirenidae) and relationships among sirenid salamanders
TLDR
The sirenid salamander Habrosaurus is revised and redescribed based on skull elements and vertebrae from the middle Campanian–middle Palaeocene of the North American Western Interior and is argued to be the geologically oldest, undoubted sirensid and the sister-taxon of Siren + Pseudobranchus.
New salamander (Amphibia: Caudata) atlantes from the Upper Cretaceous of North America
Atlantes of cf. Piceoerpeton (family Scapherpetontidae) are reported from the Lance and Hell Creek formations of Wyoming and Montana. Although smaller, they otherwise show only subtle differences…
Distribution of Proteus (Amphibia: Urodela: Proteidae) and its possible explanation

  • Environmental Science, Biology
  • 1997
TLDR
The paleogeographical and paleoclimatological data, in combination with the physiological requirements of Proteus, strongly suggest that these animals invaded the caves, at least in the NW parts of their ranges, only after the last glaciations within the last 10,000 years.
