Opis:
The Late Carboniferous amphibian genus Limnerpeton Fritsch, 1881 is revised on the basis of the type specimens of the eight original species described by Fritsch using material from Nýřany, Třemošná and Kounov, now in the Czech Republic. The type species Limnerpeton modestum is a nomen dubium restricted to a mandible that almost certainly belongs to an amphibamid temnospondyl but is not critically diagnostic. “Limnerpeton” laticeps and “Limnerpeton” macrolepis lectotypes are both small individuals of the same taxon as the later described Mordex calliprepes Steen, 1938 and thus form part of the hypodigm of Mordex laticeps comb. nov. “Limnerpeton” elegans is now Limnogyrinus elegans and is a member of the temnospondyl family Micromelerpetontidae. “Limnerpeton” obtusatum is a specimen of the microsaur Microbrachis pelikani. “Limnerpeton” dubium is an indeterminate tetrapod, probably either a temnospondyl or a pelycosaur. “Limnerpeton” difficile is a nomen dubium but the type is probably a small specimen of the tuditanomorph microsaur Crinodon limnophyes. “Limnerpeton” caducum is almost certainly a specimen of the ophiderpetontid aïstopod Oestocephalus granulosus. Several other described small temnospondyls from Nýřany are discussed and shown to be specimens of either Limnogyrinus elegans, Mordex laticeps or Amphibamidae incertae sedis. The tetrapod fauna at Nýřany includes four dissorophoid temnospondyls as proposed by Milner (1986) but with two changes in nomenclature. They comprise the branchiosaurid Branchiosaurus salamandroides, the micromelerpetontid Limnogyrinus elegans, the amphibamid Platyrhinops cf. lyelli and the primitive trematopid Mordex laticeps. These represent four of the five major dissorophoid families and demonstrate that the group had already diversified by the late Westphalian.

Opis:
Limnogyrinus elegans (Fritsch) is the most primitive micromelerpetontid temnospondyl from the Upper Carboniferous of Nýřany, Czech Republic. Arecent revision of the taxon by Werneburg (1994) attributed to this species a skull in dorsal aspect which was significantly larger than any previously reported and showed evidence of snout elongation. Restudy of this specimen demonstrates it to be a skull, visible in ventral aspect, of a juvenile of Cochleosaurus bohemicus, a more primitive edopoid temnospondyl, which is frequent in the Nýřany assemblage. Werneburg’s diagnosis of Limnogyrinusis revised and the problems of constructing ontogenetic series are discussed.

Opis:
Re−investigation of the skull roof in Metoposaurus diagnosticus from the German Middle Keuper revealed that in contrast to previous opinions, the lacrimal bone in this species enters the orbital margin.The same pattern is demonstrated by the skulls of a newly discovered metoposaur from the Keuper of Krasiejów in Poland.The difference in the shape of the parietal between the population from Krasiejów and the type population of Metoposaurus diagnosticus enables the discrimination of two separate subspecies within Metoposaurus diagnosticus.For the specimens from the Late Carnian of Drawno Beds at Krasiejów, Poland and its lateral equivalents Lehrberg Beds at Stuttgart−Sonnenberg and Kieselsandstein at Fichtenberg, Germany, a new chronosubspecies Metoposaurus diagnosticus krasiejowensis is erected.The new subspecies differs from the older nominal subspecies M. diagnosticus diagnosticus in having a shorter and wider prepineal part of the parietal.If one accepts that the nominal subspecies is the ancestor of M. krasiejowensisthe change in the shape of the parietal would be a reversal of the trend towards elongating postorbital part of the skull observed in ancestors of the metoposaurids.It seems that the skull development in ontogeny changed after the anterior shift of the orbits occurred in the phylogenetic history of the metoposaurids.The difference in ornamentation of the interclavicle between European Metoposaurus and North American genera is corroborated by Polish material.

Opis:
Fossil material from the lower Miocene collected in the basin lake of Beşkonak (Turkey) included 19 slabs showing 19 amphibian anuran tadpoles of rather large size, at Gosner stages 36–38. These well preserved specimens show many morphological and skeletal characters. They are here tentatively referred to the genus Pelobates. Two of these tadpoles show an unusual group of black roundish spots in the abdominal region, and a third similar group of spots is present in another slab but we were unable to state if it was associated with a tadpole or not. Several hypotheses can be proposed to account for these structures: artefacts; intestinal content (seeds; inert, bacterial or fungal aggregations; eggs); internal or external parasites; diseases; eggs produced by the tadpole. The latter hypothesis is discussed in detail and is shown to be unlikely for several reasons. However, in the improbable case where these spots would correspond to eggs, this would be the first reported case of natural paedogenesis in anurans, a phenomenon which has been so far considered impossible mostly for anatomical reasons (e.g., absence of space in the abdominal cavity).

Opis:
Amphibia is a class of vertebrate. Amphibians are ectothermic, or cold-blooded, and they have smooth skin that must stay moist to prevent desiccation. They play an important role in nature both, as predator and prey. Nagaland is one of the north eastern hilly states and it is very rich in biodiversity. Due to the geographical position, Nagaland has a huge number of amphibian fauna. Purpose of the present study is to get information of sociocultural relation of frog and Naga people and to study the diversity. Study was conducted through the market survey and interview. Interview was conducted among the people of different age groups which are belonging to different tribes. Frog species were collected from the markets and Morphometric measurements were taken by using a vernier caliper. Frog samples were kept as museum specimen. From the investigation, all together 11 species from 4 families were recorded from the market and identified with the help of relevant literature. Cooking procedure of frog meat among the people of Nagaland varies from tribe to tribe and people to people. Most common method of consumption is boiling with bamboo shoot. Naga people have traditional believe that frogs have medicinal purposes. Different body parts of the frog are consumed by different way to cure the various diseases. Frog eating is a traditional way and continued practice among the Naga society from the time of civilization to obtain the protein, and frogs are easily available in the markets in both, as fresh and dried. Frogs are being exploited from nature from year after year without having proper maintenance and conservation. The results of the study revealed that there is no reduction in frog population, though they are being collected in a huge number. It is necessary to culture the frog species and to establish socio-ecological system through a sustainable management and conservation of biodiversity.

Opis:
The Ypresian Cambay Shale Formation of Vastan Lignite Mine in Gujarat, western India, has yielded a rich vertebrate fauna, including the earliest modern mammals of the Indian subcontinent. Here we describe its assemblage of four frogs, including two new genera and species, based on numerous, diverse and well−preserved ilia and vertebrae. An abundant frog, Eobarbourula delfinoi gen. and sp. nov., with a particular vertebral articulation similar to a zygosphene−zygantrum complex, represents the oldest record of the Bombinatoridae and might have been capable of displaying the Unken reflex. The large non−fossorial pelobatid Eopelobates, known from complete skeletons from the Eocene and Oligocene of Europe, is also identified at Vastan based on a single nearly complete ilium. An abundant “ranid” and a possible rhacophorid Indorana prasadi gen. and sp. nov. represent the earliest records of both families. The Vastan pelobatids and ranids confirm an early worldwide distribution of these families, and the bombinatorids and rhacophorids show possible origins of those clades on the Indian subcontinent.

Opis:
Neusibatrachus wilferti is an anuran from the late Berriasian–early Valanginian fossiliferous lacustrine limestones that are exposed in the eastern part of the Montsec Range, province of Lleida, Spain. It was originally described by Seiffert in 1972 and its phylogenetic position has since been discussed. Neusibatrachus has been considered an undeterminable fossil, an abnormal individual, or a primitive palaeobatrachid. Here we redescribe the only available specimen, and clarify features, such as absence of palatines, nine presacrals, and procoelous vertebral centra, that have been the subject of previous debates. We consider the specimen to be a postmetamorphic individual and make developmental interpretations of some of its characters. In particular, we provide evidence of a living anuran (Rana iberica) that resembles Neusibatrachus in the development of intervertebral articulations. Neusibatrachus is considered a valid genus, which differs from other anurans, except for the pipoids, in the joint presence of an azygous frontoparietal and a parasphenoid lacking the subotic alae, although it differs from the pipoids in having nine presacral vertebrae. Morphological evidence indicates that Neusibatrachus is related to Xenoanura, the pipoid branch in the living Amphibia Tree of Life based on molecular data. Moreover, it might be a member of the pipoid clade proper, which presently includes the Pipidae, Rhinophrynidae, and several fossil taxa, including the Palaeobatrachidae, although the evidence is not conclusive.

Opis:
A new temnospondyl is described from the Middle-Upper Permian sequence of the Paraná Basin (Rio do Rasto Formation) in southern Brazil. The material consists of disarticulated cranial and postcranial elements, preserved in association. The cranial elements include part of the orbital region of the skull roof, the basicranium, a number of en-docranial elements, stapes and a right hemimandible. The postcranial elements include vertebrae, ribs, pectoral girdle elements, a right femur and a cluster of scales. The new species displays a rhinesuchid pattern, which is similar to the South African rhinesuchids from the Upper Permian Beaufort Group of the Karoo Basin, but differs from them by the presence of a robust and elongated epipterygoid with a blade-like anterior process in addition to elongated and deeper muscular pockets on the parasphenoid, which allow the assignment of this specimen to a new species. However, the phylogenetic analysis grouped the material described herein andAustralerpeton cosgriffi inside Stereospondylomorpha, in a transitional position between the Laurasian assemblages and South African temnospondyls. This result supports a connection between the Brazilian and Eastern European Permian fauna and provides important data for future biostratigraphic studies.

Opis:
The latest Cretaceous (Maastrichtian) fluvio−lacustrine deposits of Haţeg Basin (Romania) have yielded a number of aquatic and terrestrial microvertebrates, including dissociated skeletal remains of the following anuran taxa: Hatzegobatrachus grigorescui gen. et sp. nov., Paralatonia transylvanica gen. et sp. nov., andAnura indet. H. grigorescui sp. nov. (type species), retaining some leiopelmatid−grade anuran features, is diagnosed as a small−sized primitive frog with still unclear relationships. P. transylvanica sp. nov. (type species) is a middle−sized discoglossine frog. Based on the characters of jaw−bones andpost−cranial skeletal elements, it appears as intermediate between primitive (Eodiscoglossus−like) andmore derived (Latonia−like) discoglossine discoglossid. In Hatzegobatrachus and Paralatonia the morphology of the hipbones shows that they differ in saltatorial abilities. Consequently, these forms may have occupied distinct ecological niches, suggesting that the latest Cretaceous microvertebrate assemblages of Haţeg Basin were connectedto more complex ecosystems than considered before.
