Abstract Notobatrachus degiustoi is the most completely known Jurassic frog and has been recorded in many outcrops of the La Matilde Formation of the Deseado Massif area in southern Patagonia. Herein, we erect a new species of the genus based on partially articulated remains collected from the Callovian Las Chacritas Member of the Cañadón Asfalto Formation, about 500 km northwest of the northern limit of the known geographical distribution of N. degiustoi. The new species differs from the… 
New fossil anurans from the Lower Cretaceous Sasayama Group of Hyogo Prefecture, Western Honshu, Japan
Abstract We describe two well-preserved and articulated fossil anurans excavated from the Lower Cretaceous Sasayama Group in Hyogo Prefecture, Western Honshu, Japan, as new taxa on the basis of
A New Crown-Group Frog (Amphibia: Anura) from the Early Cretaceous of Northeastern Inner Mongolia, China
TLDR
A new crown-group frog taxon is named and described from the Lower Cretaceous Guanghua (upper part of Longjiang) Formation exposed in Dayangshu Basin, Hulunbuir, in the far northeast of Inner Mongolia, China, extending the geographic range of Early Cret Jurassic frogs of the Jehol Biota northward to near the 50th parallel north in East Asia.
A Middle Jurassic heterodontosaurid dinosaur from Patagonia and the evolution of heterodontosaurids
TLDR
A new ornithischian dinosaur from the Middle Jurassic Cañadón Asfalto Formation in central Patagonia, Argentina is reported, and derived features of its anatomy indicate that Manidens belongs to Heterodontosauridae, as the sister taxon of HeterODontosaurus and other South African heterodontsaurids.
Carpus in Mesozoic anurans: the Early Cretaceous anuran Genibatrachus from northeastern China
TLDR
Genibatrachus may fill the gap in the evolutionary sequence of the carpus between Paleozoic temnospondyl amphibians and modern frogs, and may be reconstructed from the morphological details of its ultimate constituents.
Jurassic tetrapods and flora of Cañadón Asfalto Formation in Cerro Cóndor area, Chubut Province
TLDR
The fossil record of this formation represents the most completely known biota from the continental Middle to Late Jurassic of the Southern Hemisphere and one of the most complete of the entire world.
Anurans from the Lower Cretaceous Jehol Group of Western Liaoning, China
TLDR
Comparisons with other Mesozoic and extant anurans and the primary phylogenetic analysis both suggest that Liaobatrachus is a member of the anuran crown- group and forms a polytomy with leiopelmatids (Ascaphus and Leiopelma) and the remaining crown-group anuran (LalagobatRachia).
JURASSIC FISHES OF GONDWANA
The Jurassic is an important period for understanding the origin of modern fish faunas, since it saw the first radiation - and in some cases the origin - of most modern groups. In chondrichthyans,

Phylogeny of Paleozoic limbed vertebrates reassessed through revision and expansion of the largest published relevant data matrix
TLDR
Even in its revised state, the matrix cannot provide a robust assessment of the phylogeny of early limbed vertebrates, and approaches to coding, methods of phylogenetics, and prospects for further improvement are discussed.
Jurassic Paleoclimates in Argentina, a review
New paleoclimatic evidence from palynologic and vertebrate proxies provides more detailed data on climatic change during the Jurassic in Argentina. Comparison with paleomagnetic data shows that the

A new frog (Amphibia: Anura) from the Lower Cretaceous of western Liaoning, China
TLDR
A phylogenetic analysis suggests that the new frog described from the Early Cretaceous Yixian Formation of China is a primitive archaeobatrachian closely related to NotobatRachus and Vieraella, while Neusibatrachus is placed as a basal member of the Pipoidea.

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
Osteology and relationships of a new theropod dinosaur from the Middle Jurassic of Patagonia
:  A new taxon of theropod dinosaur is described as Condorraptor currumili gen. et sp. nov., from the Middle Jurassic (Callovian) Canadon Asfalto Formation of Chubut Province, Argentinean Patagonia.
A new look at an old frog: the Jurassic Notobatrachus Reig from Patagonia
TLDR
This study revealed variation in the morphology of the adult sacral region, this variation being more evident among the specimens from one of the localities, as well as some data on the osteogenesis of this evolutionarily significant taxon.
Mesozoic anurans from Liaoning Province, China, and phylogenetic relationships of archaeobatrachian anuran clades
TLDR
The new taxon named and described in this paper is placed as the representative of a distinct archaic anuran clade, and Callobatrachus is considered to be an ingroup member of the Discoglossidae, constituting the earliest record of the family from Asia.
NOTICIA SOBRE UN NUEVO ANURO FOSIL DEL JURASICO DE SANTA CRUZ (PATAGONIA)
When Notobatrachus degiustoi was discovered, a very important step in the history of the order Anura was filled with that find, the first record of the true frogs in the world was established in the
HANDBUCH DER PALÄOHERPETOLOGIE—ENCYCLOPEDIA OF PALEOHERPETOLOGY 4
Frogs constitute a distinctive group of vertebrates; their peculiar anatomy enables the lay public to distinguish them from all other tetrapods easily. The anuran fossil record shows that by the
Initial Diversification of Living Amphibians Predated the Breakup of Pangaea
TLDR
A robust molecular phylogeny based on the nuclear RAG1 gene as well as results from a variety of alternative independent molecular clock calibrations suggest that the origin and early divergence of the three living amphibian orders dates back to the Palaeozoic or early Mesozoic, before the breakup of Pangaea, and soon after the divergence from lobe‐finned fishes.
